Question : In the rectangular cross sectional prismatic cantilever beam free end given in the figure, the P force and the weight of the cross section are variable. As it is known that P force acts perpendicular to the beam axis,

a-) What is normal stress value caused by bending moment at point A for θ=35 degree?

b-) What is the value of the angle θ that will maximize the normal stress caused by the bending moment?

c-) The location and value of the maximum normal stress caused by the bending moment calculated in part b ?
