Question 2: (6 points) Suppose we have a uniform beam that is 4 metres long, and is simply supported with a pin support at 1.25m and a roller (or rolling pin if you prefer) support at 2.75m as per the diagram below. 4m A ☆ 1.25m 2.75m If the beam has a load of f(1) = 250 N/m is applied to it, and has a flexual rigidity of 35,000 Nm?, then: a) (4 points) Calculate the deflection function y(x) for this beam assuming small deflections. b) (2 points) Is (1+(du/dr)?) 1 accurate to 4 decimal places for all 0 < x < 4? Note: 2 -1 accurate to 4 decimal places means that 2-11 < 0.00005. 3/2
