A steel tube with a circular cross section has an outside diameter of 310 mm and wall thickness of 2 mm. The cylinder is twisted along its length of 2 m with a torque of 54 kN.m. NOTE: This is a multi-part question. Once an answer is submitted, you will be unable to return to this part. Determine the maximum torsional shear stress using the equation Tmax = T.

For the stresses given with the cube below: 1. Compute the center, radius (R), principal normal stresses (0₁ and 03), max shear stress (Tmax) and draw the Mohr's Circle. 2. Compute the normal and shear stresses when the cube is rotated 20° clockwise from the horizontal plane and draw them on the cube. 3. The yield point stress (σyp) is 6 kPa. Determine if the material will fail under stresses shown using Tresca's Hexagon. вкра акра 6 экра 8 кра экра 4кра

Please help with the stress, mohir circle, etc. Thank you

A shaft of diameter d is guided in rotation at A (bearing 1) and C (bearing 2) and carries two wheels supporting the indicated loads, The radius of wheel B is 200 mm, and of wheel D is 100mm. The shaft is made of steel. F2 = 6000 N. Dimensions are in mm. Calculate the diameter (mm) of the shaft considering an allowable stress of 270 MPa for a stress composed of bending and torsion.
