MCQ->The crane provides a long-reach capacity by using the telescopic boom segment DE. The entire boom is supported by a pin at A and by the telescopic hydraulic cylinder BC, which can be considered as a two-force member. The rated load capacity of the crane is measured by a maximum force developed in the hydraulic cylinder. If this maximum force is developed when the boom supports a mass m = 6 Mg and its length is l = 40 and = 60°, determine the greatest mass that can be supported when the boom length is extended to l = 50 m and = 45°. Neglect the weight of the boom and the size of the pulley at E. Assume the crane does not overturn. Note: when = 60° BC is vertical; however, when = 45° this is not the case.....

MCQ->S1: A force of exists between everybody in the universe. P : Normally it is very small but when the one of the bodies is a planet, like earth, the force is considerable. Q : It has been investigated by many scientists including Galileo and Newton. R : Everything on or near the surface of the earth is attracted by the mass of earth. S : This gravitational force depends on the mass of the bodies involved. S6: The greater the mass, the greater is the earth's force of attraction on it. We can call this force of attraction gravity. The Proper sequence should be:....
