Questions and Answers
  • 1. 

    According to Lam, what's the purpose of engineering drawing?

  • 2. 

    What do oblique and isometric drawings have in common?

  • 3. 

    Why was Brunellshi's contribution to drawing important? In your answer, describe his contribution.

  • 4. 

    Lam Loc creates drawings to help engineers communicate their ideas more effectively through the use of __________________ , otherwise known as CAD.

    Explanation
    The correct answer is "Computer-Aided Design". Lam Loc creates drawings to help engineers communicate their ideas more effectively through the use of CAD, which stands for Computer-Aided Design. CAD is a software tool that allows engineers to create, modify, analyze, and optimize designs digitally. It helps in visualizing and simulating the final product, making the communication of ideas easier and more efficient.

    In an _____________ drawing, the front side of the object appears flat in the picture plane and the sides and top of the object are at a 45-degree angle to the horizontal lines of the front side.

    Explanation
    In an oblique drawing, the front side of the object is shown as a flat representation on the picture plane, while the sides and top of the object are depicted at a 45-degree angle to the horizontal lines of the front side. This technique provides a three-dimensional appearance to the object while still maintaining a clear view of the front side.

    The imaginary point on the horizon in which an object's parallel lines appear to converge is called the __________________.

    Explanation
    The vanishing point is the term used to describe the imaginary point on the horizon where parallel lines of an object appear to converge. It is a concept commonly used in art and perspective drawing to create the illusion of depth and distance. When an object is viewed from a certain angle, its parallel lines seem to converge towards this vanishing point, giving the impression of three-dimensional space.

    In a ______________ drawing, the lines of the object that move away from the viewer converge on an imaginary point called the vanishing point.

    Explanation
    Perspective drawing is a technique used to create the illusion of depth and three-dimensionality on a two-dimensional surface. In this type of drawing, the lines of the object that move away from the viewer converge on a vanishing point. This vanishing point is an imaginary point where all the parallel lines seem to meet, creating a sense of depth and distance in the drawing.

    In an ______________ drawing all vertical lines are drawn at 30 degrees to the horizontal, allowing engineers to communicate measurements of an object.

    Explanation
    An isometric drawing is a type of drawing where all vertical lines are drawn at 30 degrees to the horizontal. This type of drawing allows engineers to accurately communicate measurements of an object. It provides a three-dimensional representation of an object, showing all three dimensions (length, width, and height) in a single view. By using isometric drawings, engineers can convey the shape, size, and proportions of an object, making it easier for others to understand and interpret the measurements.

    _______________ refers to the ratio of an object in a drawing to the size of the object in real life.

    Explanation
    Scale refers to the ratio of an object in a drawing to the size of the object in real life. It is used to represent the proportional relationship between the dimensions of the drawing and the actual object. Scale is commonly used in architecture, engineering, and design to accurately depict the size and proportions of objects in a visual representation. It allows for accurate measurements and ensures that the drawing is a true representation of the real-life object.

  • 10. 

    The ratio of the size of the drawing and the size of the object is called the _______________.

    Explanation
    The ratio of the size of the drawing to the size of the object is known as the scale factor. This factor determines how much the drawing has been scaled down or up in relation to the actual size of the object. It helps to establish the relationship between the dimensions of the drawing and the dimensions of the object being represented.

  • 11. 

    The _________________ is a system of measurements in which the standard unit for length is one meter.

    Explanation
    The metric system is a measurement system that uses the meter as the standard unit for length. It is a decimal-based system that is widely used around the world, particularly in scientific and international contexts. The metric system provides a consistent and easily convertible framework for measuring length, mass, volume, and other quantities. It is known for its simplicity and ease of use, making it a preferred choice in many fields of study and industry.

    A(n) _______________ drawing is a 2D, or flat, drawing of each side of an object used to communicate the dimensions of a design.

    Explanation
    An orthographic drawing is a 2D representation of an object that shows each side of the object separately. It is commonly used in design to communicate the dimensions and details of an object.
