Bennett Mechanical Test Springs and Elasticity 3

Question 1

In a car suspension system, coil springs are used primarily to:

Accepted Answer

Absorb road shocks and maintain tire contact

Answer

Increase vehicle speed

Answer

Steer the vehicle

Answer

Transfer engine power to the wheels

Question 2

Which statement correctly describes springs connected in series?

Accepted Answer

They experience the same force but have different extensions

Answer

They have the same extension but different forces

Answer

Each spring's force adds to give total force

Answer

The total extension equals the smallest individual extension

Question 3

What material property makes steel well-suited for manufacturing springs?

Accepted Answer

High elastic limit and ability to return to its original shape

Answer

High density

Answer

Low melting point

Answer

Magnetic permeability

Question 4

A spring scale (like a hanging fish scale) operates on the principle that:

Accepted Answer

Extension is proportional to applied force

Answer

Weight is proportional to volume

Answer

Gravity varies with temperature

Answer

Mass equals weight times volume

Question 5

When a valve spring in an engine is compressed by the camshaft, what form of energy is stored in the spring?

Accepted Answer

Elastic potential energy

Answer

Kinetic energy

Answer

Thermal energy

Answer

Chemical energy

Question 6

If a spring is cut in half, what happens to the spring constant of each piece?

Accepted Answer

It doubles

Answer

It is halved

Answer

It remains the same

Answer

It quadruples

Question 7

Which of the following best defines the elastic limit of a spring?

Accepted Answer

The point beyond which permanent deformation occurs when force is removed

Answer

The maximum length a spring can physically reach

Answer

The minimum force needed to begin stretching a spring

Answer

The energy stored at maximum safe compression
