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.

Ejercicio 4/100

4/100 In the special position shown for the log hoist, booms AF and EG are at right angles to one another and AF is perpendicular to AB. If the hoist is handling a log weighing 4800 lb, compute the forces supported by the pins at A and D in this one position due to the weight of the log.
