Problem $8$

In the shown Figure the arm $AB$ is connected to the rod BC and is loaded at A as shown. You are required to:

i$.$ Determine the internal reaction components at sec$.$ a$-$a$.(secC)$ that is made of a hollow cylinder of outer diameter $50$ mm and an inner diameter of $40$ mm $.$

ii$.$ Determine the position of the most heavily stressed point in that section.

iii. Determine the stress components at the most heavily stressed point in that section, and hence determine the principal stresses at this point.
