Spring Deflection

What are the variable factors in a vehicle suspension system?

• Spring rate and damping coefficient

• Engine size and horsepower

• Tire pressure and tread pattern

• Fuel type and consumption

Which type of spring compresses in a linear way?

• Linear spring

• Progressive spring

The role of damping in a vehicle suspension system is to:

• absorb shocks and vibrations

• increase the speed of the vehicle

• reduce the weight of the vehicle

• improve fuel efficiency

A spring generates a restoring force when deflected by an external force because:

• it stores potential energy when compressed or stretched.

• it loses energy when compressed or stretched.

• it changes its mass when compressed or stretched.

• it generates heat when compressed or stretched.

What happens to the mass when it is deflected by an external force according to the diagram?

• The mass increases

• The mass decreases

• The mass remains the same

• The mass is destroyed

True or False: The inertia of the mass will make it continue past its 'at rest' position, generating another restoring force.

• True

• False

What is the term used to describe the reduction in amplitude due to internal friction and air resistance?

Fill in the blank: The restoring forces will make the mass continue to oscillate either side of the 'at rest' position at a constant ________.

• frequency

• velocity

• amplitude

• displacement

What is the formula for the frequency of oscillation in hertz (Hz)?

What is the deflection of a coil spring when a 10 kg mass is applied?

• 1 cm

• 2 cm

• 3 cm

• 4 cm
