Part $2$:

a$)$ What is the shear stress for the brass slab tested in parts $1.$a$-$c$?$

b$)$ If the cross section is changed to an I$-$beam with the given dimensions, what is the shear flow and

shear stress at point a$?$

c$)$ If they test a W$14$x$38$ beam, what would be the shear flow at the flange? What would be the shear

stress in the x$-$axis at the centroid of the beam? What would be the flexural stress in the flange?
