The steel member shown in the figure below has a torque of 90  N.m and an axial load of 9000N

applied to it with one end being fixed. The lengths are L= 500 mm L1=200 , and L2=140

and the diameters are d=50 and D=110

1. Calculate the maximum tensile stress along with the location and direction.
2. Calculate the maximum compressive stress along with the location and direction.
3. Calculate on the cross-section the maximum in-plane shear stress along with the location and direction.
4. Also identify the point where absolute maximum shear stress takes place and calculate the same with the direction.
5. 

A shaft is subjected to a maximum torque of 14 KN-m and a maximum bending moment of 10 KN- m at 
a particular section. Determine the diameter of the shaft according to maximum shear stress theory if the 
elastic limit in simple tension is 180 MPa

A wood beam 1.8 m long is simply supported at its ends, has a cross-section 15cm wide by 60cm deep and carries a uniformly distributed load of intensity w = 8000 kg/m over the full span. Calculate the bending stress at a point 20cm above the bottom of the beam and 60cm from the left support & also find out the maximum bending stress for this beam.
