Name: ______________________ Class: _________________ Date: _________ ID: A Suspension Systems Chapter 6 True/False Indicate whether the statement is true or false. 1. Semi-independent suspensions are used on the rear of many front-wheel drive cars. 2. Springs carry the weight of the vehicle and absorb shock forces. 3. Leaf springs typically accompany MacPherson strut suspensions. 4. The motion of compression and extension, in a shock absorber, is converted into heat energy and dissipated into the atmosphere. 5. Lateral acceleration is the measurement of the vehicles ability to accelerate in a straight line. Multiple Choice Identify the choice that best completes the statement or answers the question. 6. What occurs when a wheel hits a dip or hole and moves downward? a. jounce c. deflection b. free length d. rebound 7. What controls the up-and-down movement of a vehicle as it moves down a bumpy road? a. struts c. both “struts” and “shock absorbers” b. shock absorbers d. neither “struts” nor “shock absorbers” 8. Coil spring designs and ratings are being discussed. Technician A says coil springs may have a linear rate. Technician B says coil springs may have a variable rate. Who is correct? a. A only c. both A and B b. B only d. neither A nor B 9. Strut designs are being discussed. Technician A says in the conventional MacPherson strut, the coil spring surrounds the upper part of the strut.
