In the wheel suspension of a car, the spring motion is provided by a torsio n bar fastened to the arm on which the wheel is mounted. The torque in the torsion bar is created by the 2500 N force acting on the wheel from the gro und through a 300 mm long lever arm. Because of space limitations, the bear ing holding the torsion bar is situated 100 mm from the wheel shaft.
How can I find The diameter of the torsion bar and how to find the stresses in the torsion bar at the bearing by using the DET theory? also the materi al to be used to manufacture the bar.
