A Variable Value Units WI W 1.8 [m] D Wa W W A truck (mass = m) is loaded with two crates of equal mass (mass = m), one at each end of the bed as shown. The truck's centre of mass is at point G and both the front and rear wheels act as roller supports. W2 2.7 [m] W W3 1.7 [m] 2) The reaction at the rear wheel, point A, [kN], (3 sigfig) Given the information in the table above, determine: 1) The reaction at the front wheel, point B, [kN] (3 sigfig) B W4 1.2 [m] W5 0.75 [m] m 1300 [kg] m 350 [kg] g 9.81 [ms-2] 3) If the crate D was removed, what is the maximum mass of crate C before the front wheels (point B) lift up? [kg], (3 sigfig)
