A hollow steel shaft with an outside diameter of do = 4.1 in. will be subjected to a pure torque of T = 3750 lb-ft. Using the classic theory of torsion, determine the maximum inside diameter in inches that can be used if the shear stress must not exceed [T] = 8000 psi. Please, give correct answer to two decimal place.

A solid steel bar with a circular cross-section has diameter 50 mm, length 1.5 m and shear modulus of 80 GPa. If the allowable shear stress is 48 MPa and the allowable angle of twist is 2.0 degrees, then what is the maximum permissible torque? State your answer in Nm to 1 decimal place.

The hollow shaft used in the system has the following conditions: Outer Ø:110 mmØ Allowable Shearing Stress:85 MPa Determine the thickness (mm) of the shaft. Round to the nearest whole number for the thickness and use 2 decimal places for other solved values. Provide a torque diagram, strictly follow instructed sign convention, and start from left to right.

A steel shaft 2542 mm long must transmit a torque of 34 KN-m. The total angle of twist and the maximum shearing stress must not exceed 3 degree and 110 MPa respectively. Find the diameter of the shaft that meets there conditions. Check based on strength and rigidity. Use G = 78268 MPa. Use two (2) decimal places.

A flanged bolt coupling consists of eight d-mm diameter steel bolts on a bolt circle 261 mm in diameter, and four d-mm diameter steel bolts on a concentric bolt circle 194 mm in diameter. If the torque that can be applied is 8728 Nm without exceeding a shearing stress of 52.59 MPa in the bolts, what is the diameter of the bolts? Round off the final answer to two decimal places.

The four rigid gears, loaded as shown in the figure, are attached to a 3.23-in.-diameter steel shaft. Compute the angle of rotation of gear A relative to gear D if TA = 496 lbft, TB = 830 lbft, and TC = 1193 lbft. Use G = 12068762 psi for the shaft. Round off the final answer to four decimal places.
