An open circular ring of circular cross section (with diameter d) is subject to two equal and
opposite out-of-plane tip forces Q as shown. Find the relative displacement of the two ends
of the ring. Note that you must consider both the work of bending and torsion. Estimate the
relative contributions of bending and torsion to the relative displacement.-

EXAMPLE 5.4
A solid steel shaft AB,shown in Fig. 5-11, is to be used to transmit 5 hp from
the motor M to which it is attached. If the shaft rotates at e = 175 rpm and
the steel has an allowable shear stress of 7,llow = 100 MPa determine the
required diameter of the shaft to the nearest mm.

SOLUTION
The torque on the shaft is determined from Eq. 5-10, that is, P = To.
Expressing Pin watts and o in rad/s, we have
