Question

Considering the bar with a uniform cross-sectional area shown in the figure. This bar is fixed to the wall, and a vertical force, F, is applied at its end, with a value of 400 N. It is known that l = 300 mm and m = 150 mm. The bar has a diameter of 25 mm.

a) Which position on the bar (point) is subjected to the highest stress? Justify your answer.  
b) For the position defined in item 'a,' calculate the state of plane stress.
c) Applying the maximum shear stress theory, determine if there is a prediction of yielding.
d) Applying the distortion energy theory, determine if there is a prediction of yielding.
