The two solid shafts are connected by the gears shown.
The motor constantly supplies 20 kW of power at 15 Hz to
system at A. The yield shear stress is 140 MPa for shaft (1) and
220 MPa for the shaft (2), and over all factor of safety is 2.
a) Find the diameter of both shafts.
b) If the modulus of rigidity of shaft (2) G is 77.2 GPa,
calculate the relative angle of twist D with respect to C.
