1.58 The crankshaft of a single-cylinder air compressor rotates 1800 rpm. The piston area is 2000 mm2 and the piston stroke is 50 mm. Assume a simple “idealized” case where the average gas pressure acting on the piston during the compression stroke is 1 MPa, and pressure during the intake stroke is negligible. The compressor is 80% efficient. A flywheel provides adequate control of the speed fluctuation. a) What motor power (kW) is required to drive the crankshaft? b) What torque is transmitted through the crankshaft?
28. The shaft shown in Figure P5-28 is supported by bear-
ings at each end, which have bores of 20.0 mm. Design
the shaft to carry the given load if it is steady and the
shaft is stationary. Make the dimension a as large as pos-
sible while keeping the stress safe. Determine the required

FIGURE P5-28 (Problems 28, 29, and 30)
The motor shown operates at constant speed and develops a torque of 100 lb-in during normal
operation. Attached to the motor shaft is a gear reducer of ratio 5:1, that is, the reducer output
shaft rotates in the same direction as the motor but at one-fifth motor speed. Rotation of the
reducer housing is prevented by the "torque arm" pin-connected at each end as shown. The
reducer output shaft drives the load through a flexible coupling. Neglecting gravity and friction,
what loads are applied to (a) the torque arm, (b) the motor output shaft, and (c) the reducer
output shaft?
