Question

Determine:

a) State of stress at point A on the upper surface of the shaft

b) The maximum normal stresses at point A as we well as its orientation 

c) Of the 800lb force is going upwards (instead of downwards) explain what will happen to i) normal stress, and ii) shear stress at A (no calculations needed for part c)

The bracket shown is fixed
supported at the wall. Two point
loads are applied at its free end. a)
determine state of stress at point A
on the upper surface of the shaft. b)
determine the maximum normal
stresses at point as well as its
orientation c) if the 800lb force is
going upwards (instead of
downwards) explain what will
happen to i. normal stress and ii.
shear stress at A (no calculations
needed for part c).
