Question 1 1. A solid shaft of 1.55 m is used as a tractor propeller (prop) shaft. The shaft twists through 1.8 while rotating at 900 rpm. The diameter of the shaft is 60 mm and the modulus of rigidity is 85 GPa. Calculate 1.1 The maximum shear stress in the shaft 1.2 The power transmitted by the shaft. 2. The tractor has undergone minor modifications to increase the transmitted power by 20%. The solid shaft is replaced by a lighter hollow shaft of the same material, with a dimeter ratio of 2:1. Calculate the suitable dimeters of the hollow shaft.

Use Area Moment Method of Beam Deflections

Determine rotations at all the nodes of the beam and reactions at the supports.  Assume support 1 and 3 are roller and support 2 is pinned,  L1=1.25m, L2=3.75m and w=60kN/m. Please show all working and FBD's where relevant.
