A 6.6 EXAMPLE 2
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 an extruded section, the lengths 'b' are found this way
Since b/t is greater than 10, alpha and beta are 1/3. Therefore, maximum shear stress is
