For the I$-$beam section shown in the figure, a shearing force V of $150$ kN and a bending

moment M of $200$kN$-$m act over the section. Determine the maximum and minimum

values of bending stress and transverse shear stress in the vertical web of the section.

Here,

Second moment of area I$\_($ZZ$)=389$ xx$10^(6)$mm$^(4)$

Hint: To figure out the maximum and minimum transverse shear stress, you need to

find out the first moments of the areas until that point. Remember the transverse

stress variation in l$-$beam section solved in the class to understand where the stress

will be maximum$/$minimum$.$

a$)$ What is the value of maximum transverse shear stress in MPa $($give until $2$ decimal places$)$

b$)$ What is the value of minimum transverse shear stress in MPa $($give until $2$ decimal places$)$

c$)$ What is the value of maximum bending stress in MPa $($Give until $2$ decimal places$)$

d$)$ What is the minimum value of bending stress in MPa?
