1. The endurance limit for rotating shaft, if its ultimate strength Su=1600 Mpa is:

What is the over-turning moment at x = 0, of a hollow tube that has an OD of 40 mm, and an ID of 20 mm. The length of the tube is 960 mm. It is attached to a 1 inch thick plate.

Please and thank

I am struggling with this question

PLEASE ANSWER PART 4 and 5 Part 1 Calculate the polar moments of inertia in segments (1) and (2). Answer: J₁ = 13.84 in.⁴ J₂= 1.535 in. ⁴ Part 2 Calculate the internal torques T1 and T2 in shaft segments (1) and (2), respectively. On paper, prepare an internal torque diagram for the compound shaft that shows these internal torques. Use the sign convention presented in Section 6-6. Answer: T₁ = 800 Ib-ft, T₂= -800 Ib-ft. Part 3 Calculate the maximum shear stress in each shaft segment. On paper, prepare a diagram that shows the maximum shear stress in segments (1) and (2) of the shaft. Use the sign convention presented in Section 6-6. Answer: τ₁ = 1560.69 psi, τ₂ = -7817.59 psi Part 4 (PLEASE ANSWER) Determine the rotation angle of B with respect to the support at A. Please Answer: φB= rad. Part 5 (PLEASE ANSWER) Determine the rotation angle of C with respect to the support at A. Please Answer: φC= rad.

The three configs are A, B, and C in the picture

When a solid steel shaft is subjected to a torque of 45,000 in-lbs, the maximum shear stress is 8,000 psi. Find the diameter of the shaft and compute the angle of twist in a length of 5 feet.
