Determine the minimum width, w, of the beam that will safely support the loading P = 7 kip. The beam is 36 ft long from the pin support to the point where P is applied, 6 in tall, has a rectangular cross-section, and made of a material that has a maximum allowable bending stress of o allow = 24 ksi and a maximum allowable shear stress of Tallow = 0.5 ksi.

Question
Please solve and circle correct answer ignore part C thanks
S= I/c.
Once a loading is specified, we can use the flexure formula with
the maximum bending moment, Mmax , to specify a lower bound
on the section modulus:
Determine the minimum width, w, of the beam that will safely support the loading P=7 kip. The beam is 36 ft long from the pin support to the point where P
is applied, 6 in tall, has a rectangular cross-section, and made of a material that has a maximum allowable bending stress of oallow = 24 ksi and a maximum
allowable shear stress of Tallow = 0.5 ksi. (Figure 2)
Express your answer to three significant figures.

Where the maximum bending stress, oallow, is a parameter
generally given in the design specifications.

is generally less specific than the bending-moment specification,
so it is used as the secondary design consideration.
