An automobile weighing 3000 lb is slowed down uniformly from 40 to 10 mph is a distance of 100 ft by a brake on the drive shaft. Rear wheels are 28 – inches in diameter. Differential ratio is 40:11. Neglecting tire, bearing, and gear losses, determine the minimum size of the drive shaft if the shear stress on the drive shaft is not to exceed 25 ksi.

Question
An automobile weighing 3000 lb is slowed down
uniformly from 40 to 10 mph is a distance of 100 ft by a
brake on the drive shaft. Rear wheels are 28 – inches in
diameter. Differential ratio is 40:11. Neglecting tire,
bearing, and gear losses, determine the minimum size of
the drive shaft if the shear stress on the drive shaft is not
to exceed 25 ksi.
