Numerical Problem $(20$ points$)$: A gantry crane is an overhead crane that has one or two beams supported by free$-$standing legs and moves on heels, a track, or rail system carrying a bridge, trolley, and hoist. Gantry cranes are used in warehouses and shipyards to lift and carry heavy objects, and are possibly the most important structure$/$system in logistics$.$ Your Amazon parcel is handled by multiple gantry cranes each day so that it gets transported safely to you. In turn, for this problem, you will analyze a beam for one such gantry crane in an Amazon warehouse to

ensure that you understand everything about the internal forces in this beam and make it safer for the people

working in the warehouse. Draw the SFD and BMD for the gantry crane beam shown below using the method of

sections. Please make sure you provide numerical values of shear force and bending moment at locations where

the loading changes $)$ and where the shear force and bending moment has the maximum positive and

negative magnitudes.
