Pictured below is a smooth bar (no friction) held in position by a pin and contact with the wall on the left end and subjected to a vertical load P at the right end. Find the distance d that the force needs to be along the bar for equilibrium given the pin is a distance a away from the wall and the bar makes an angle 0 with the horizontal. The weight of the bar is negligible. (Hint: Use the three equations of equilibrium and solve for d. The values for a, e, and Pare constants.)

This is a mechanics of material question please show all steps clearly please show the given, what is to be found, and a free body diagram.

A cylindrical pressure vessel having a radius r = 14 in. and wall thickness t = 0.375 in. is subjected to internal pressure p = 375 psi. In addition, a torque T = 90 kip-ft acts at each end of the cylinder (see figure). (Assume that the structures behave linearly elastically and that the stresses caused by two or more loads may be superimposed to obtain the resultant stresses acting at a point. Consider both in-plane and out-of-plane shear stresses unless otherwise specified.) (a) Determine the maximum tensile stress omay and the maximum in-plane shear stress Tmay in the wall of the cylinder. (Enter the magnitudes in ksi.) o, = ksi Tmax ksi (b) If the allowable in-plane shear stress is 4.5 ksi, what is the maximum allowable torque T? (Enter the magnitude in kip-ft.) kip-ft (c) If T = 150 kip-ft and allowable in-plane shear and allowable normal stresses are 4.5 ksi and 11.5 ksi, respectively, what is the minimum required wall thickness (in inches)? in.

The beam is made from a soft linear elastic material having a constant EI. If it is originally a distance  from the surface of its end support, determine the length a that rests on this support when it is subjected to the uniform load w0, which is great enough to cause this to happen.
