Explanation / Answer

A) Maximimum bending stress equation:

M * y = sigma * I

where, M=banding moment , y=distance of neutral axis from the extreme, sigma=maximum stress developed, I=moment of inertia of the cross section

y = 1.5 in

sigma = 140 Ksi

I = [2 * 3^3]/12 = 4.5 in^4

--> M = 140 * 4.5 /1.5 = 420 Kip.in = 34.986 Kip.ft

B)

M = 180 * 4.5 / 1.5 = 540 Kip.in = 44.982 Kip.ft
