An automobile can be considered to be mounted on four identical springs as far as vertical oscillations are concerned. The springs of a certain car are adjusted so that the oscillations have a frequency of 2 Hz. (a) What is the spring constant of each spring if the mass of the car is 1250 kg and the weight is evenly distributed over the springs? My Work: ω = 2πf = 2π(2Hz) = 12.56637061 rad/s; k = mω2 = [1250kg(12.56637061 rad/s)^2]/4...

Problem 3. A plate is resting on four identical helical compression springs at its four corners. The plate is loaded centrally so that each of these springs undergoes same amount of deflection. For safety, a much harder spring is placed at the center of the plate. The free lengths of the softer springs are 20 mm more than the harder one. Corner Springs Center Spring Mean Diameter, D 40 mm 25 mm Wire Diameter, d 5 mm 5 mm Active...
