Homework Statement
High strength steel hollow shaft which can withstand complex stresses generated by a combo of loading conditions. Tresca yield criterion is to be used as the basis of design with a factor of safety of 1.5. Shaft is of 50mm and 40mm outer and inner diameters and is subjected to the following loading condition:Torque: 2.5kNm about axis
An axial tensile load of 50kN offset vertically by e (15mm) from axis.
A bending moment of 3.6kNm acting on vertical plane containing cylinder axis and eccentric load line of action.
1) Determine the sizes of direct and shear stresses acting at point A on the outer surface of the shaft (right through the middle)and mark them on the element.
Homework Equations
for a hollow shaft I found these equations: J = pi (D^4 - d^4) / 32tau max = Torque*radius / J, I = pi(D^4-d^4)/64
