PROBLEM 3.58 Solve Prob. 3.57, assuming that the 80-N · m torque is applied to end C of shaft CD. PROBLEM 3.57 At a time when rotation is prevented at the lower end of each shaft, a 50-N · m torque is applied to end A of shaft AB. Knowing that G = 77.2 GPa for both shafts, determine (a) the maximum shearing stress in shaft CD, (b) the angle of rotation at A.
Ten years ago, DEWA, an electricity and water authority, issued $20 million worth of municipal bonds that carried a coupon rate of 6% per year, payable semiannually. The bonds had a maturity date of 25 years. Due to a worldwide recession, interest rates dropped significantly enough for the utility to consider paying off the bonds early at a 10% penalty to the face value. DEWA would then reissue the bonds at the same face value (i.e., $20 million) for the remaining 15 years, but at a lower coupon rate of 2% per year, payable semiannually. What would be the semiannual rate of return to DEWA, if it proceeds with this plan?
