ForWDL = 3 kN/m, WLL= 16 kN/m, A = 2000mm2, I = 200 x 106mm4, and E = 200,000 MPa (200kN/mm2); calculate the moment envelope values and plot the moment envelope curves(positive and negative). (NOTE: You only need to consider maximum positive and negative bending moments even though for a true envelope curve you would have to consider all pointsbetween the supports.)
