Truck suspensions often have "helper springs" that engage at high loads. One such arrangement is a leaf spring with a helper coil spring mounted on the axle, as in the figure below. The helper spring engages when the main leaf spring is compressed by distance yo, and then helps to support any additional load. Consider a leaf spring constant of 6.05 x 105 N/m, helper spring constant of 3.60 x 105 N/m, and y₁ = 0.500 m. Ⓒ Truck body m WWW.C Axle (a) What is the compression of the leaf spring for a load of 4.55 X 105 N? (b) How much work is done compressing the springs?
