The torques shown are exerted on pulleys A and B. Consider TA = 270 N·m and TB = 400 N·m. Knowing that both shafts are solid, determine the maximum shearing stress in shaft BC. The maximum shearing stress in shaft BC is ____ MPa.

A 2550-N·m torque T is applied to the hollow shaft as shown.   Determine the diameter of a solid shaft for which the maximum shearing stress under the loading shown is the same as in part (a).   The diameter of the solid shaft is ____ mm.

A hollow steel drive shaft (G = 11.2 × 106 psi) is 8 ft long and its outer and inner diameters are respectively equal to 2.50 in. and 1.25 in. Know that the shaft transmits 200 hp while rotating at 1570 rpm.Determine the maximum shearing stress (Ksi)

Determine the maximum shearing stress (MPa) in a solid shaft of 60-mm diameter as it transmits 91 kW at a speed of 175 rpm.

A flanged bolt coupling consists of eight steel 20-mm bolts spaced evenly around a bolt circle of 300mm in diameter. Determine the torque capacity of the coupling if the allowable shearing stress in the bolts is 40MPa

Determine the torque T that causes a maximum shearing stress of 70 MPa in the steel cylindrical shaft shown

A steel shaft must transmit 150 kW at a speed of 360 rpm. Knowing that G = 77.2 GPa, design a solid shaft so that the maximum shearing stress will not exceed 50 MPa and the angle of twist in a 2.8-m length must not exceed 3°. Consider the frequency f to be 6 Hz. The diameter of the solid shaft is  -- mm

The preliminary design of a motor-to-generator connection calls for the use of a large hollow shaft with inner and outer diameters of 4 in. and 6 in., respectively. Knowing that the allowable shearing stress is 12 ksi, determine the maximum torque that can be transmitted by (a) the shaft as designed, (b) a solid shaft of the same weight, and (c) a hollow shaft of the same weight and an 8-in. outer diameter.

Two solid steel shafts are connected by the gears shown. Knowing that for each shaft G= 11.2 * 106 psi and the allowable shearing stress is 8 ksi, determine (a) the largest torque T0 that may be applied to end A of shaft AB and (b) the corresponding angle through which end A of shaft AB rotates.
