Theory of Machine Which of the following statement is correct as regard to the difference between a machine and a structure? A machine transforms the available energy into some useful work, whereas in a structure no energy is transformed into useful work All of these The parts of a machine move relative to one another, whereas the members of a structure do not move relative to one another 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 All of these The parts of a machine move relative to one another, whereas the members of a structure do not move relative to one another The links of a machine may transmit both power and motion, whereas the members of a structure transmit forces only ANSWER DOWNLOAD EXAMIANS APP
Theory of Machine In a cam drive with uniform velocity follower, the sharp corners of the displacement diagram are rounded off at the beginning and at the end of each stroke. This is done Because of loose contact of follower with cam surface Because of difficulty in manufacturing cam profile Because the uniform velocity motion is a partial parabolic motion In order to have acceleration in beginning and retardation at the end of stroke within the finite limits Because of loose contact of follower with cam surface Because of difficulty in manufacturing cam profile Because the uniform velocity motion is a partial parabolic motion In order to have acceleration in beginning and retardation at the end of stroke within the finite limits ANSWER DOWNLOAD EXAMIANS APP

Theory of Machine When the load on the engine increases, it becomes necessary to increase the supply of working fluid and when the load decreases, less working fluid is required. The supply of the working fluid to the engine is controlled by a Governor Flywheel Meyer's expansion valve D-slide valve Governor Flywheel Meyer's expansion valve D-slide valve ANSWER DOWNLOAD EXAMIANS APP
