Theory of Machine Which of the following statement is correct as regard to the difference between a machine and a structure? All of these The links of a machine may transmit both power and motion, whereas the members of a structure transmit forces only A machine transforms the available energy into some useful work, whereas in a structure no energy is transformed into useful work The parts of a machine move relative to one another, whereas the members of a structure do not move relative to one another All of these The links of a machine may transmit both power and motion, whereas the members of a structure transmit forces only A machine transforms the available energy into some useful work, whereas in a structure no energy is transformed into useful work The parts of a machine move relative to one another, whereas the members of a structure do not move relative to one another ANSWER DOWNLOAD EXAMIANS APP

Theory of Machine The relation l = (2/3).(j + 2) apply only to kinematic chains in which lower pairs are used. This may be used to kinematic chains in which higher pairs are used, but each higher pair may be taken as equivalent to One lower pair and two additional links Two lower pairs and two additional links Any one of these Two lower pairs and one additional link One lower pair and two additional links Two lower pairs and two additional links Any one of these Two lower pairs and one additional link ANSWER DOWNLOAD EXAMIANS APP
Theory of Machine In a four-bar chain it is required to give an oscillatory motion to the follower for a continuous rotation of the crank. For the lengths of 50 mm of crank and 70 mm of the follower, determine theoretical maximum length of coupler. The distance between fixed pivots of crank and followers is 95 mm Slightly more than 95 mm Slightly less than 95 mm 45 mm 95 mm Slightly more than 95 mm Slightly less than 95 mm 45 mm ANSWER DOWNLOAD EXAMIANS APP
