Problem $3$

The $T$ beam shown is subjected to a downward shear force of $600N.$ Its cross section has a

neutral axis located $120mm$ measured from the bottom and the moment of inertia of the section

about the horizontal axis is $I=27\mathrm{.}0{10}^{-6}{m}^4$ :

a$)$ Calculate the maximum shear stresses in the section. Where is it located?

b$)$ Draw the shear stress distribution for this section clearly showing values, distances and

type of function. No need to calculate other values $($only max and min$)$ and the moment of inertia is $I=27\mathrm{.}0{10}^{-6}{m}^4.$
