2. The figure below shows a shaft with pulley and gear.
Find the location along the x axis where the normal and shear stresses are the greatest. Create an
element drawing of the stress state at this location. Find the principal stresses.
Hints:1. the shaft diameter is not given, but you can find the stresses as a function of diameter.
2. Because the shaft is rotating, the maximum normal stress can be determined by using the resultant
moment.

Q3/ Two shaft is attached to a rigid wall at each end. For the bronze segment AB. the diameter
is 75 mm and G = 35 GPa. For the steel segment BC, the diameter is 55 mm and G = 83 GPa.
Given that a-2 m and b-1.5 m. compute the largest torque T that can be applied as shown in
the figure if the maximum shear stress is limited to 60 MPa in the bronze and 80 MPa in the
steel.
