Question $4$

Find the Absolute Maximum Bending Moment. For a simply supported beam, the absolute maximum bending moment occurs under one of the wheels when the distance between that wheel and the resultant of the wheel group is bisected by the midpoint of the beam

$($i$)$ Find the resultant of the wheel load

$($ii$)$ Find the distance of the resultant from the left $(3$ kips$)$ wheel.

$($iii$)$ Find the maximum bending moment. In other words, if you were to place this wheel group on the simply supported beam $($span $=64ft)$ such that the midpoint of the beam $=32)$ were halfway between a wheel and the resultant, the maximum bending moment would occur under that wheel
