A hollow cylindrical shaft was designed to have a uniform wall thickness of 0.1 in. Defective fabrication, however, resulted in the shaft having the cross section shown. Knowing that a 17-kip-in. torque is applied to the shaft, determine the shearing stresses at points a and b. 2.4 in. 0.08 in. 1.1 in. 0.12 in. The shearing stress at point a is The shearing stress at point b is ksi. ksi.

3. A tube 2 mm thick has the shape shown in the figure Find the shearing stress caused by a torque of 600 N m. (Practice at Home) 10 mm - 80 mm 10 mm

Due to loading, the plate is deformed into the dashed shape shown in the figure. Assume a = 39 in., b= 33 in., δ1= 0.1625 in., δ2= 0.1 in. Determine the average normal strain along the side AB?in micro rad And answer in right and clear way Determine the average shear strain in the plate at A relative to the horizontal and vertical axes?

The copper pipe shown in the figure has an outside diameter of 4.000 in. and a wall thickness of 0.363 in. The pipe is subjected to a uniformly distributed torque of t = 80 lb-ft/ft along its entire length. Using a = 2.00 ft, b = 4.00 ft, and c = 7.5 ft, calculate (a) the shear stress at A on the outer surface of the pipe. (b) the shear stress at B on the outer surface of the pipe. a b Answers: (а) ТА i psi (b) Тв- i psi
