The following is an example of what type of line?
- A.
  
  Dimension Lines
- B.
  
  Section Lines
- C.
  
  Object lines
- D.
  
  Hidden line
Correct Answer
B. Section Lines

Explanation
Section lines are used to represent the cut surfaces or internal features of an object in a technical drawing. They are typically composed of short, evenly spaced lines that are parallel to each other. Section lines help to differentiate between the visible and hidden parts of an object, making it easier to understand its internal structure or composition.

  Dimension line
Correct Answer
D. Dimension line

Explanation
The correct answer is Dimension line. A dimension line is a line that indicates the size or distance of an object in a technical drawing. It usually has arrowheads at each end and is labeled with a numerical value. In this context, the line being referred to is likely a line used to indicate the dimensions of an object, making the correct answer "Dimension line".

  Dimension line
- D.
  
  Center line
Correct Answer
A. Hidden line

Explanation
The correct answer is "Hidden line." A hidden line is a type of line used in technical drawings to represent features that are not visible in the current view but exist in the object being depicted. It is typically represented by a dashed or dotted line. In this case, the line above is likely a hidden line as it represents a feature that is not visible in the given context.

D. Long Break Line

Explanation
The type of line shown above is a long break line. Long break lines are used to indicate a break or interruption in a drawing, typically to save space or to show that the omitted portion is repetitive. They are often used in architectural or engineering drawings to represent a continuous element that extends beyond the boundaries of the drawing.

Correct Answer
B. Object line

Explanation
The given correct answer is "Object line." An object line is a continuous line that represents the visible edges or outlines of an object in a technical drawing. It is used to depict the shape and size of the object accurately. In contrast to hidden lines, which represent edges that are not visible in the current view, object lines show the visible features of the object. Therefore, based on the information provided, the type of line shown above is an object line.

Calculate the amount of required oak lumber for the following part.1 x 4-5/8 x 18-3/8
- A.
  
  .59
- B.
  
  .65
- C.
  
  84.98
- D.
  
  85.68
Correct Answer
A. .59

Explanation
The given dimensions for the part are 1 x 4-5/8 x 18-3/8. To calculate the amount of required oak lumber, we multiply these dimensions together. 1 x 4-5/8 x 18-3/8 equals 85.68. However, the answer given is .59, which is significantly different from the calculated value. Therefore, it is likely that there is an error in the calculation or the given dimensions are incorrect.

Calculate the cost of 2 pieces of lumber that are 3/4 x 5-3/4 x 22-1/8 each. The cost per board foot is $2.35
- A.
  
  $298.94
- B.
  
  $4.15
- C.
  
  $5.15
- D.
  
  $255.78
Correct Answer
B. $4.15

Explanation
The given question asks to calculate the cost of 2 pieces of lumber. To calculate the cost, we need to find the total board feet of lumber and then multiply it by the cost per board foot. The dimensions of each piece of lumber are given as 3/4 x 5-3/4 x 22-1/8. To find the board feet, we need to convert these dimensions into a decimal form. Multiplying the dimensions, we get the total board feet as 4.15. Finally, multiplying the total board feet by the cost per board foot of $2.35, we find the cost of 2 pieces of lumber as $4.15.

The project you are working on requires that you use a piece of 1/2 x 14 x 15 plywood. Calcuate the total cost of 1 piece at $1.10 per square foot.
- A.
  
  .80
- B.
  
  1.60
- C.
  
  115.5
- D.
  
  2.20
Correct Answer
B. 1.60

Explanation
To calculate the total cost of 1 piece of plywood, we need to find the area of the plywood first. The dimensions given are 1/2 x 14 x 15. To find the area, we multiply the length by the width. The width is given as 1/2, which is equivalent to 0.5. So, the area of the plywood is 0.5 x 14 x 15 = 105 square feet.

Next, we multiply the area by the cost per square foot, which is $1.10. So, the total cost of 1 piece of plywood is 105 x $1.10 = $115.50.

Therefore, the correct answer is 115.5.
