Question
Completely solve and box the final answers. Write legibly.
Note: Please pardon me, if you can answer all of the numbers please do so, because if I ask the questions separately it will the same thing that the expert will also need to solve the first number to solve the preceding numbers. I hope for your very deep understanding. Thank you.

1. If the beam cross section is a rectangle with a breadth and
depth of 6 in and 8 in respectively, what is the bending
stress?
2. If the beam cross
section is a rectangle with a breadth and
8 in respectively, what is the shear
depth of 6 in and
stress?
3. If the beam cross section is circular with diameter of 8
in, determine the shear stress.
4. Compute for the midspan value of Ely in lb. ft³
5. Considering the following design conditions for the beam:
Allowable bending stress: 20000 psi
Allowable shear stress: 10000 psi
Maximum allowable deflection: L/360
