Please help me solve the attached problem determining the magnitudes of forces and torque in a cylinder.

Please show all steps so that I may see what I'm leaving out. Thanks

Please help with these 3 problems involving bending moments, shear, and unit stresses.

Please solve showing your work, so that I may see what I'm leaving out.

Please help me solve the attached problem determining the magnitudes of forces and torque in a cylinder. (please show your work)

Please solve the attached problem, showing your work, so that I can study the steps. A) torque - 8000 lb-in B) force - 133.33 lb The above torque and force calculations are from an Online TA that solved the problem, but didn' t show his/her work.

Determine Maximum allowable load

A rigid steel plate is supported by three posts of high-strength concrete each having an effective cross-sectional area A=40,000 mm^2 and Length L=2 m (see attachment). Before the load P is applied, the middle post is shorter than the others by an amount s=1.0 mm. Determine the maximum allowable load Pallow if the allowable compressive stress in the concrete is equal to 20 MPa.(Use E=30 GPa for concrete) THE ANSWER SHOULD BE 1.8 MN

Mass Fractions

For the following problem, can I get the full solution (show your work) with explanation as to how you arrived at the answer. For a lead-tin alloy of composition 80 wt% Sn-20 wt% Pb and at 180 degrees Celsius (355 degrees Farenheit) do the following: a) Determine the mass fractions of alpha and beta phases b) Determine the mass fractions of primary beta and eutectic microconstituents c) Determine the mass fraction of eutectic beta
