This suggests that there is a specific location for the drawing table and it is not arbitrary or irrelevant.

The given answer states that "A 5" is smaller than "A 4". This means that "A 5" is a smaller format compared to "A 4".

The symbols represent the minimum and maximum permissible roughness.

The correct answer is D because wavy lines are used to represent breaks or interruptions in objects when they are drawn manually.

The given correct answer is A. Pokazane bez błędów (Shown without errors). This suggests that the holes shown in both the view and the section are accurate and do not contain any mistakes or discrepancies.

The symbols Ra1.25, Ra10, Ra5, etc. on the engineering drawing indicate the height of surface roughness. This means that they represent the average distance between the highest and lowest points on the surface of the pump cover. These symbols are used to specify the desired level of smoothness or roughness required for the surface finish.

The red arrows have been crossed out because it is unnecessary to include all dimensions as the closed chain already contains redundant dimensions derived from other given dimensions.

The correct answer is C because there is an error visible in Projection III. The error is that the top surface of the object is not shown in the projection.

The recommended way of dimensioning views is shown in drawing b.

Drawing a) is poorly dimensioned, while drawing b) is well dimensioned.

The correct answer is C. Skrajne położenie wyłącznika krańcowego. This is indicated by the dotted line on the diagram, which represents the extreme position of the limit switch. The limit switch is a device that is used to detect the presence or absence of an object and is often used to control the movement of machinery or equipment. In this case, the dotted line indicates the maximum or minimum position that the limit switch can reach.

The correct answer is B. Rysunki dolne dobrze. This means that the lower drawings are correct. The question is asking for the correct way to use cross-sections in the above screw and coupling connections. Since the drawings in the lower part of the question are labeled as "dobrze," which means "good" or "correct" in Polish, it can be inferred that these drawings show the proper use of cross-sections in the given connections.

For formats A3 and smaller, the framing of the drawing area should be 5 mm.

The symbol in the upper right corner of the drawing represents the roughness class.

The correct answer is A. 50:1, 20:1, 10:1, 5:1, 2:1. This answer is correct because it lists the scales in descending order, starting with the largest scale (50:1) and ending with the smallest scale (2:1). These scales are commonly used in engineering graphics to represent the ratio between the size of an object on paper and its actual size.

The given correct answer, C. Tolerancja i pasowanie wałka według - e8, means that the final dimension of the shaft is specified with a tolerance and fit of - e8. This indicates that the shaft must be manufactured within certain limits to ensure proper fit and function with other components. The e8 tolerance and fit standard provides specific guidelines for the size and fit of the shaft, ensuring that it will work correctly in the intended application.

The correct answer is A because the question asks for the "basic drawing format in engineering graphics" and the answer states that it is "the yellow format A4". This suggests that the yellow A4 format is commonly used and considered as the standard or foundational format in engineering graphics.

The correct answer is B because it states that in drawing b, the most dimensions are given in the section. This implies that the section view provides the most detailed and accurate representation of the dimensions in the drawing.

The correct answer is C. Linia gwintu w połączeniu gwintowym (Thread line in threaded connection). The explanation for this answer is that the given description mentions a 3/4 circle drawn with a thin line inside the lower part of the construction element. This indicates the presence of a threaded connection, where the thread line is represented by the 3/4 circle. Therefore, option C is the correct answer.

The correct answer is C because it accurately describes the definition of "kład" as the outline of a flat figure located in the plane of the cross-section of an object, rotated along with that plane by 90º and positioned either within or outside the object's outline.

The correct answer is B. Rzut aksonometryczny prostokątny. This is because an axonometric projection is a type of orthographic projection that shows an object in three dimensions. In this type of projection, the object is rotated to show all three axes (length, width, and height) equally foreshortened. A rectangular axonometric projection specifically shows the object in a rectangular frame, with the three axes forming equal angles with the plane of the frame.

The given example a) and b) are examples of projection type E (European).

The interrupted lines in the view drawing above represent invisible edges of the object. These lines indicate edges that are not visible from the current viewpoint but are present in the object. They are used to provide a complete representation of the object's shape and structure.

The correct answer is A. Rzutowania prostokątnego. This is because the question asks for the name of the given method of projection, and "rzutowanie prostokątne" translates to "orthographic projection" in English. Orthographic projection is a method of representing a three-dimensional object in two dimensions by projecting lines from the object onto a plane.

The correct answer is D. This is because the given drawing is dimensioned correctly according to the acceptable standards and practices.

The correct answer is B because the drawing shows two parallel planes with a tolerance for perpendicularity. The lines in the drawing indicate that the two planes should be perpendicular to each other within a certain tolerance. This means that the two planes should be at right angles to each other, with no significant deviation from perpendicularity.

The correct answer is B. 0.18 mm ; 0.5 mm ; 1.0 mm. This is because the question asks for the thickness of thin, thick, and very thick lines. The measurements given in option B match these criteria, with 0.18 mm being the thickness of a thin line, 0.5 mm being the thickness of a thick line, and 1.0 mm being the thickness of a very thick line.

The correct answer is C. Łożysko kulkowe w przekroju i pierwszym stopniu uproszczenia. This is because the image shows a cross-section of a ball bearing, which is a type of rolling element bearing used to support rotational motion. The simplified representation in the image only shows the first stage of the bearing, where the balls are located between the inner and outer raceways.

The correct answer is C. Kład. The element A in the highlighted area represents a floor or a platform, which is commonly referred to as a "kład" in Polish. It is a horizontal surface that people can walk or stand on.

In technical drawing, a "pismo techniczne pochyłe" refers to an oblique lettering style. The question asks at what angle this oblique lettering should be drawn from the horizontal level. The correct answer is D. 75 degrees from the horizontal level. This means that the oblique lettering should be slanted at a 75-degree angle from the horizontal line.

The above drawing shows an example of a welded connection, where the upper body is joined to the lower body.

The correct answer is C. j) k). The question asks for the tolerance of radial and axial runout, and the drawings that represent these tolerances are j) and k).

The given correct answer is A. Rysunku złożeniowego, which translates to "assembly drawing" in English. This type of drawing shows how different parts or components fit together to form a complete assembly. In the context of the question, the drawing of the tensioner belt is showing how different parts of the belt tensioner are assembled together.

To calculate the module of a gear, the number of teeth and the pitch diameter (diameter of the pitch circle) are needed. The pitch diameter is the diameter of the imaginary circle that passes through the center of the gear teeth and is used to determine the gear ratio. The pitch diameter can be calculated using the pitch diameter formula, which includes the pitch diameter (d), the number of teeth (z), and the module (m). Therefore, the correct answer is B. Średnica podziałowa – d (Pitch diameter - d).

The correct answer is A. Jest nagwintowany do połowy (It is half-threaded).

The elements marked with numbers "2", "4", and "7" in the above schematic represent fuel pumps.

The correct answer is C, which states that there are no errors in the dimensioning. This means that there are no mistakes or inaccuracies in the way the dimensions are represented in the drawing.

In the given question, the correct answer is D. W przykładach a) oraz b) - prawe rysunki są dobrze wykonane. This means that the correct way of drawing the cross-sections of the given connections is shown in the right drawings of examples a) and b). The left drawings in both examples are not correctly executed.

The given drawing represents a fragment of a threaded pin, also known as a threaded shaft or bolt. The shape and features of the object in the drawing closely resemble those of a threaded pin, indicating that it is most likely a fragment of a threaded pin.

The drawings above represent different types of couplings.

The correct answer is B. Rysunków przekrojów aksonometrycznych. This is because "przekrojów aksonometrycznych" translates to "axonometric sections" in English, which refers to a type of drawing technique that combines both oblique and orthographic projections. This type of drawing is often used in technical and architectural drawings to show the internal structure of an object or building.

The correct answer is D. Tolerancję równoległości dwóch płaszczyzn. This is because the image (b) shows two parallel planes, indicating the tolerance for parallelism between the two surfaces.

The given correct answer is C. Bicia osiowego (wzdłużnego) części maszyn względem osi otworu mierzonej na średnicy 100 mm. This means that the tolerance shown in the diagram represents the axial (longitudinal) displacement of machine parts relative to the axis of the hole measured on a diameter of 100 mm.

The above drawing represents a simplified level I:A. Screw connectionB. Screw system with a springC. Telescopic-spring connectionD. None of the above connectionsThe correct answer is B because the drawing shows a combination of screws and a spring, indicating that it is a screw system with a spring.

The correct answer is C because the module of a gear is calculated by dividing the pitch diameter of the gear by the number of teeth.

The correct answer is B because the question asks whether the H7 tolerance for a 200 mm diameter hole means that the dimension of 200 mm can be larger by 0.021 mm from the nominal value. The statement in the question states that the tolerance for a 20 mm hole is 0.021 mm, but it does not imply that the same tolerance applies to a 200 mm hole. Therefore, the H7 tolerance for a 200 mm diameter hole means different allowable deviations.

The symbol (e) on the drawings indicates that there should be gaps in the welding of lengths "e".

The given drawing represents a simplified view of a gear wheel.

The correct answer is C. Moduły obydwu kół zębatych muszą być takie same. This means that in order for two gears to work together without interference, the modules of both gears must be equal. The module of a gear is a measure of the size of its teeth and determines the spacing and size of the teeth on the gear. If the modules of the gears are not the same, the teeth will not mesh properly and will cause interference or incorrect operation. Therefore, for smooth and efficient operation, the modules of both gears must be the same.
