A mobile crane is lifting a large concrete block W at a constuction site, as shown in the figure below. The crane body has a weight of W₁ = 8500 lb and the crane boom has a weight of W₂ = 1000 lb, which act at the centers of gravity CG₁ and CG₂ respectively. The center of gravity locations (L₁ & L₂), the distance between the front and rear tires (L3), and the location of the lifting weight (L₁) are given as follows: L₁ = 45 in L2 = 95 in, L3=110 in, and L4 = 125 in. Note: Express your answers following the standard sign convention for the coordinate system shown. L₂ y Lox ΝΑ = NB- = 2 Al W maz CG₁ L3 (a) If the block weighs W - 2800 lb, find the combined reactions at both rear tires (A) and both front tires (B). lb ? lb ? B number (rtol=0.01, atol=1e-05) number (rtol=0.01, atol=1e-05) CG₂ L4 W (b) Determine the maximum weight Wmaz that the crane can lift before tipping over. number (rtol=0.01, atol=1e-05) lb ?
