A mechanic uses a crowfoot wrench to loosen a bolt at E. Knowing that the mechanic applies a vertical 20-lb force at A, determine the principal stresses and the maximum shearing stress magnitude at point H located as shown on top of the -in. diameter shaft. (Round the final answers to two decimal places.) E 6 in. B V 10 in. The maximum principal stress is Omax |ksi and the minimum principal stress is Omin |ksi (+ tensile; - compressive). The maximum shearing stress magnitude is |ksi.

How do I solve this using Mohr’s Circle

Determine the number of main bars, spacing, and determine the spacing for stirrups.

The control arm is subjected to the loading shown. The allowable shear stress for the steel pin is τ = 10 ksi. Determine the required diameters of the steel pins at A and C. Write your final answer to the nearest three decimal places.
