Suspension Fundamentals

1. If a spring loaded with 200 pounds compresses 1 inch, how far would it compress if it were loaded with 300 pounds?

• 1 inch

• 1.5 inches

• 2 inches

• 3 inches

Which term describes the scenario in which a spring is compressing as the vehicle moves down and the suspension moves up?

• Jounce

• Rebound

• Expansion

• Resistance

1. Which vehicle would seem to have the lowest centre of gravity?

• A full-size SUV

• A lifted pickup truck

• A cargo van

• An F1 race car

What is the best definition of sprung weight?

• Weight of parts support by the vehicle's suspension

• Weight of parts NOT supported by vehicle's suspension

• Weight of parts not secured to vehicle

• Weight of non-essential components on the vehicle

What is the key result of minimizing unsprung weight?

• Make suspension system heavier and stronger

• Lower the vehicle's centre of gravity

• Make suspension lighted and more reactive

• Reduce the potential centrifugal force

Which type of friction is harder to overcome?

• Static

• Kinetic

• Rolling

Which two surfaces would you expect to have the lowest coefficient of friction?

• Rubber and Concrete
• Ice and Teflon
• Wood and Metal
• Glass and Sandpaper

What component is commonly used to change sliding friction into rolling friction?

• Spring steel

• Friction bearing

• Non-friction bearing

• Drag link

Spring steel has low yield strength

• True

• False

Which component would you expect to be made of spring steel?

• Torsion bar

• Crankshaft

• Valve train components

• Wheel rim
