Figure 1 shows a simple system to lift a heavy load. The dimensions a = 3.6 m and b = 1.2m. The mass of the bar and counterweight is 45000 g, and their weight W acts at the pointas shown. The mass of the load being lifted is20000g(a)(b)If the load is just above the ground, determine the vertical force the person mustexert to support the system.If the load is 1 m above the ground, determine the vertical force the person mustexert to support the system.25°Figure 120000 gW

given : W = 20000 g = 20kg CW = 45000 g = 45 kg
