A 20-mm diameter rod made of a ductile material with a yield strength of 350 MPa is subjected to torque of 100 N.m and a bending moment of 150 N.m.
An axial force is then gradually applied. Determine the value of force when the rod begins to yield.
Solve the problem two ways using the (a) Tresca theory (Maximum shearing stress theory) and (b) von Mises theory (Maximum distortion energy theory).

Determine the total mass of nitrogen (N2), in kg, required to inflate all four tires of a vehicle, each to a gage pressure of 180 kPa at a temperature of 25oC. The volume of each tire is 0.6 m^3, and the atmospheric pressure is 1 atm.
The beam AB has a built-in support at A. The roller support at B allows vertical deflection but prevents rotation. Determine all the support reactions.
Hydrogen is contained in a piston-cylinder device at 14.7 psia and 15 ft3. At this state, a linear spring (Flux) with a spring constant of 15,000 lbf/ft is touching the piston but exerts no force on it. The cross-sectional area of the piston is 3 ft2..
