Question

5-30. The motor A delivers 50 hp while turning at a constant rate of 1350 rpm. Using the belt and pulley system this power is delivered to the steel blower shaft BC. Determine to the nearest $\frac{1}{8}$ in. the smallest diameter of this shaft if the allowable shear stress for steel is $\tau_{allow} = 12$ ksi.

Step 1

Step 1: The power delivered by the motor is given by: $$P = \frac{2\pi NT}{60}$$ where: * $P$ is the power in horsepower (hp) * $N$ is the speed in revolutions per minute (rpm) * $T$ is the torque in pound-feet (lb-ft) Show more…
