Question: homework assignment two identical elastic shaft segments are connected to...

Question details

Homework Assignment Two identical elastic shaft segments are connected to a rigid disk acted on by a moment m, as illustrated in Figure 2.38(a). To reduce the rotation angle at O by 40%, the design of Figure 2.38(b) is used instead of the original one. Assuming all shaft segments are built from the same material and have constant circular cross sections, express the diameter d2 in terms of the diameter di, and the lengths l and l2. Also calculate the value of d2 for di-0.012 m, -0.24 m, and 12-0.16 m 2.4 Flexible shat Flexible shatRigid disk FIGURE 2.38 Fixed-Fixed Shaft With (a) Two Identical Segments, (o) Two Pairs of Identical Segnents
