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?

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

Problem Statement: Given the diagram of gears A and D connected to rods BC and EF. There is a given torque of 5 kip*in for   and   is unknown. The shafts of rods ABC and DEF are solid and their diameters are unknown. Each shaft has an allowable shearing stress of 8500psi

Question Statement:

Using the known values find the required minimum diameter a) of shaft BC and b) shaft EF
