Ejercicio 4/97

4/97 The machine shown is used for moving heavy items such as pallets of bricks around construction sites. For the horizontal boom position shown, determine the force in each of the two hydraulic cylinders AB. The mass of the boom is 1500 kg with mass center at G1, and the mass of the cube of bricks is 2000 kg with mass center at G2.
