Question
The four gears shown are attached to a steel
shaft that is rotating at 2 Hz. Gear B supplies
70 kW of power to the shaft. Of that power, 20kW
are used by gear A, 20 kW by gear C and 30kW
by gear D.

(a) If a uniform shaft diameter of 125 mm
B speci fied, detenmine the angle of rotation
of A relative to D.
O f segment Co is to be replaced lay a hollaw
Shaft with an inside diameter of 80 mm,
what is the outside diameter if the stress
is not to excced 70 MPa.
