Determine the diameter of a steel shaft, in inches, if subjected to a torque of 36,000 in-lbs and a shear stress of 10 ksi.

A compound shaft consists of brass segment (1) and aluminum segment (2). Segment (1) is a solid brass shaft with an outside diameter of 0.51 in. and an allowable shear stress of 4500 psi. Segment (2) is a solid aluminum shaft with an outside diameter of 0.41 in. and an allowable shear stress of 6000 psi. Determine the magnitude of the largest torque TC that may be applied at C. Express your answer in lb-in rounded to the nearest tenths.

1. Calculate the stress set up in a thin flywheel rim,one meter in diameter,made of steel density 7.86g/cm³,when rotating at 1500rev/min.

PLEASE ANSWER ASAP TY! The shaft shown has a diameter of 30 mm and is fixed at points A and B.  Shear Modulus = 75 GPa.  a) What is the internal torque in segment AC (in N-m)? b) Determine the maximum torsional shear stress experienced at segment AC (in MPa). c) What is the torsional shear stress  at the center of the cross-section of the shaft (in MPa)? d) Determine the reactive torque at point B (in N-m).
