Section A6.6 example 1 SECTION A 6.6 EXAMPLE 1

Use the formulas based on the theory of elasticity to find the maximum shear stress and angle of twist per unit length of a bar having the cross sectional shape shown below.

EQUATIONS USED

SOLUTION

First, need to find the b/t ratio. Because this is a formed section, the lengths 'b' are found this way

Since b/t is greater than 10, we can let alpha and beta be 1/3. Therefore maximum shear stress is

Angle of Twist per unit length is
