a$)$ When governed by the maximum normal stress within the beam, the magnitude of the maximum P is$\_\_\_\_\_$ kips.

b$)$ The magnitude of $"$A$\_$web" is $\_\_\_\_\_$ in$^2.$

c$)$ When governed by the maximum shear stress within the beam, the magnitude of the maximum P is$\_\_\_\_\_$ kips.

d$)$ Assume the maximum allowable P is applied to the beam.

$$

The magnitude of the shearing force at $2\mathrm{.}75$ft to the left of support C is$\_\_\_\_\_$ kips.

e$)$ Assume the maximum allowable P is applied to the beam.

$$

The magnitude of the maximum shear stress at $2\mathrm{.}75$ft to the left of support C is$\_\_\_\_\_$ ksi.
