Physics · Solid Mechanics
A circular solid shaft of span L = 5 m is fixed at one end and free at the other end. A torque T = 100 kN·m is applied at the free end. The shear modulus and polar moment of inertia of the section are denoted as G and J, respectively. The torsional rigidity GJ is 50,000 kN·m2/rad. The following statements are reported for this shaft: Statement i) The rotation at the free end is 0.01 rad. Statement ii) The torsional strain energy is 1.0 kN·m. With reference to the above statements, which of the following is true?
