Question 3:(5 points)For the beam in Question 2,suppose that instead of the pin support,we instead have a clamped (fixed)support on the left edge as per the diagram below.4mOm2.75mWhich of the two beams has more maximum magnitude of deflection,and by how much (assuming smalldeflections)?Question 4:(3 points,Challenge)For the beam in Question 2 find the optimal placement of supports thatminimises the maximum magnitude of deflection if he supports are equidistant from their respective ends(i.e.,if the pin support is em from the left end,then the roller support is (m from the right end).You may use a spreadsheet for this question only.Upload your spreadsheet if you use one.You must stillalso show mathematical working.
