2.) A truck with axle loads of W = 19.6kN and W2 = 78.6kN on a wheel base of d = 4.3m rolls across the beam shown in the figure. Determine the following: 3m 25 m 22 m a.) Draw the influence line for the shear at C - 10pts b.) Draw the influence line for the moment at midspan of BC - 10pts c.) The maximum positive moment (kN-m) at the midspan of BC-5pts d.) The maximum negative moment (kN-m) at the midspan of BC-5pts e.) The maximum negative shear (kN) that can be developed in the beam-5pts
