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.
