Hey Maths forum!

I got another mechanics question I hope you are able to help.

For the diagram attached below,

1) what is the shear stress for the cross section perpendicular to the length of the beam

2) assuming a right-handed axis system with+xto the right and+yup. determine the stressxon the section titled as shown.

3) assuming a right-handed axis system with+xto the right and+yup. determine the stressyon the section titled as show

4) assuming a right-handed axis system with+xto the right and+yup. determine the shear stressxyon the section titled as show

kind regards,
