1. The solid shaft shown is formed of a brass for which the allowable shearing stress is 90 MPa. Neglecting the effect of stress concentrations, (a) determine the smallest diameters dəb and dec of the shafts AB and BC, respectively. The maximum shearing stress not to exceed the allowable. (b) determine the angle of twist at A, B. and C. 60 mm TB= 1000 N.m TB = 1500 N.m Tc=500 N.m 36 mm dab B TA= 750 N.m 250 mm 700 mm dBC C 375 mm 500 mm 400 mm Problem #1. Problem #2 2. The Brass rod AB (G= 39 GPa) is bonded to the hallow Aluminum rod BD (G=27 GPa). Assuming both rods are solid calculate the angle of twist at A, B, C and D.
