In order to create a strong shaft that could withstand a great amount of torque while acquiring it in low cost, an engineer made a composite shaft. The said composite shaft is comprised of an inner solid steel shaft 1/6 ft in diameter slipped over with a hollow bronze shaft of 1/4 ft outer diameter and 1/6 ft inner diameter and of the same length as the steel shaft. The two shafts are then fastened rigidly together at their ends. What torque can be applied to the composite shaft without exceeding a shearing stress of 12,000 psi in the steel or 8000 psi in the bronze?

In order to create a strong
shaft that could withstand a
great amount of torque while
acquiring it in low cost, an
engineer made a composite
shaft. The said composite
shaft is comprised of an inner
solid steel shaft 1/6 ft in
diameter slipped over with a
hollow bronze shaft of 1/4 ft
outer diameter and 1/6 ft
inner diameter and of the
same length as the steel
shaft. The two shafts are then
fastened rigidly together at
their ends. What torque can
be applied to the composite
shaft without exceeding a
shearing stress of 12,000 psi
in the steel or 8000 psi in the
bronze?
