Answer 1

False

Question 2

Which dimension should be given for the diameter of a spring on a drawing?

A)inside
B)outside
C) radial
D) both A and B

Answer 2

D

Question 3

If a bumper was to be made of a spring, a torsion spring would be recommended.

Answer 3

False

Question 4

Section lining is illustrated in a large spring where the cutting plane line passes through the center axis of the spring by filling the coils in solid.

Question 5

If the coil winding direction is not called-off on the drawing, it will be manufactured as:

A)left-hand winding
B)right-hand winding
C) the same as other springs in the drawing
D) none of the above

Question 6

To determine the outside diameter of a spring, measure the wire size, double it, and add it to the inside diameter.

Question 7

The two general classifications of springs are helical and flat.

Question 8

A spring is a mechanical device that changes rotational force into linear force.

Question 9

To find mean diameter, subtract the wire diameter from the outside diameter.

Question 10

An extension spring would be used to return a jackhammer to its original position.

Question 11

Which spring type has only one point of contact?

A)plain open end
B)plain closed end
C) ground open end
D) ground closed end

Question 12

The solid length of a compression spring is the length of the spring stretched out straight.

Question 13

Torsion springs are commonly used to resist twisting.

Question 14

The "free length" of a spring means the overall length of a spring when it is in free state or unloaded condition.

Question 15

To measure the free length of a compression spring it must be compressed.

Question 16

Other than the required dimensions, what spring data must be noted below and to the right?

A)material
B)number of coils
C) direction of winding
D) all of the above

Question 17

Which type of spring would be required for a spring-loaded pair of wire cutters?

A)torsion spring
B)compression spring
C) expansion spring
D) extension spring

Question 18

If a cutting plane passes through the axis of a small spring, it is drawn with the section area filled in with section lines.

Question 19

To properly measure the overall length of an extension spring, measure from the inside of the loop or hook.

Question 20

The length of a spring when a specified load is applied to it is referred to as the loaded length.

Question 21

If the outside diameter is 1.50" and the wire diameter size is .25", the inside diameter is:

A)1.75"
B)1.25"
C) 1.00 "
D) can not be calculated with the information given

Question 22

In an extension spring, active coils include:

A)all coils
B)all coils minus the two end coils
C) all coils minus one of the two end coils
D) only those coils engaged in action

Question 23

Which step should be completed after drawing a rough sketch when drawing a compression spring?

A)determine the wire size to calculate the mean diameter
B)measure and construct two vertical lines for the overall length
C) measure and construct the mean diameter
D) determine the direction of windings

Question 24

Which of the following is the most stable type of compression spring?

A)ground closed end
B)plain closed end
C) ground open end
D) plain open end

Question 25

To easily represent a side view of a spring, which of the following would be recommended?

A)use a template
B)represent the coils with dashed lines
C) represent the coils with phantom lines
D) both A and B

Question 26

Which of the following is not a common use for a torsion spring?

Question 27

When gripping a left-hand spring, your:

A)right thumb should align with the coils
B)left ring finger should align with the coils
C) wrist should be parallel to the coils
D) left thumb should align with the coils

Question 28

When drawing a spring, which information should be called-off?

A)inside diameter
B)number of coils
C) wire size
D) solid length

Question 29

Which of the following is not a type of helical spring?

A)compression spring
B)flat spring
C) torsion spring
D) extension spring

Question 30

Before you begin drawing a spring, be sure to:
