Which of the following is NOT true: a. The polar moment of inertia formula is the same for all shapes and sizes O b. Torsion tends to produce a rotation

about the longitudinal axis c. Shear strain is the measurement of the change in angle in units of radians d. Torsional shear stress is equivalent to the applied torque or moment multiplied by the distance from the center to the point of interest all divided by its polar moment of inertia e. Torsion is the stress due to an applied torque or moment
