Find the stress (in MPa) in the red cylinder below. 5000 kg D₁ = 0.50m D₂=0.75m

A compound shaft consists of a titanium alloy [G = 6,200 ksi] tube (1) and a solid stainless steel [G = 11,500 ksi] shaft (2). Tube (1) has a length of L1 = 50 in., an outside diameter of D1 = 2.55 in., and a wall thickness of t1 = 0.160 in. Shaft (2) has a length of L2 = 52 in. and a diameter of d2 = 1.35 in. If an external torque of TB = 520 lb·ft acts at pulley B in the direction shown, calculate the torque TC required at pulley C so that the rotation angle of pulley C relative to A is zero.

Determine the normal stress in a ball, which has an outside diameter of 190 mm and a wall thickness of 3.1 mm, when the ball is inflated to a gage pressure of 77 kPa. Answer: 0 = i MPa

Situation The helical spring shown is axially loaded with a compression force P equal to 5 kN. The mean diameter of the spring is 100 mm and the wire used is 10 mm as indicated in the figure. 1. What is the shear stress at A? 2. What is the shear stress at B? 3. On diameter AB, locate the point of zero stress measured from C. P = 5 kN WW P = 5 kN 100mm A 10mm B
