Problem # 7: The steel shaft DF consists of three concentric tubes and is
supported by smooth bearings at D and E. It is coupled to a motor at F,
which delivers 14 kW of power to the shaft while it is running at 52 rev/
sec. The gears A, B, and C remove 3 kW, 5 kW, and 6 kW, respectively.
The shaft is free to turn in its support bearings D and F. Determine the
shearing stress developed in segments BC and CE. (
