Problem $08\mathrm{.}033-$ Determine normal and shearing stresses for a beam with rectangular cross section under axial and bending loads

The cantilever beam $AB$ has a rectangular cross section of $150200mm.$ Knowing that the tension in the cable $BD$ is $10\mathrm{.}7$ kN and neglecting the weight of the beam, determine the normal and shearing stresses at the three points indicated. $($Round the final answers to two decimal places.$)$

The normal stress at point $a$ is $q,$ MPa.

The shearing stress at point $a$ is $$

The normal stress at point $b$ is $q,$ MPa.

The shearing stress at point $b$ is $$ MPa $.$

The normal stress at point $c$ is $$ MPa.

The shearing stress at point $c$ is $$ MPa $.$ MPa.
