7. [011 Points] DETAILS PREVIOUS ANSWERS SERCP11 5.5.P.026. MY NOTES ASK YOUR TEACHER PRACTICE ANOTHER 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 shown in the gure below. When the main leaf spring is compressed by distance yo, the helper spring engages and then helps to support any additional load. Suppose the leaf spring constant is 5.10 x 105 N/m, the helper spring constant is 3.50 x105 N/m, and yU = 0.500 m. Q , ,., (a) What is the compression of the leaf spring for a load of 4.50 x 105 N? 0.3197 3' Your response differs from the correct answer by more than 10%. Double check your calculations. m (b) How much work is done in compressing the springs? :IJ
