The shaft is to have a cross section such that its inner diameter and outer diameter are related by d;=0.8do. Determine these required dimensions if the allowable bending stress is allow=155 MPa. 15 kN/m 60 kN - m di do A 1 m 3 m

The lap joint is connected together using a 32 mm diameter bolt. Determine the permanent shear strain in the shear plane of the bolt when the applied force P = 750 kN is removed. Note: The bolt is made from a material having a shear stress-strain diagram as follows T (MPa) A { 600 400 5 50 y (10³ rad)

Dont round off initial values, round off final ans only pls

Determine the safe load of the column section shown, if it has a yield strength of 25 MPa. E = 200000 MPa. Use NSCP Specifications.
