Problem R4.1[edit]

Figure from Mechanics of Materials textbook.
Mechanics of Materials: 6th Edition textbook. Authors: F.P BEER, E.R. JOHNSTON, J.T. DEWOLF AND D.F. MAZUREK ISBN:9780077565664.

Problem statement: A motor exerts a torque to shaft FGH attached to a gear with radius which in turn applies a torque to a gear with radius attached to shaft CDE. No slipping occurs between the gears. The Allowable shearing stress in each shaft is .

Question statement:

What is required diameter of shaft CDE?
What is required diameter of shaft FGH?
