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 Slightly less than 95 mm 45 mm Slightly more than 95 mm 95 mm Slightly less than 95 mm 45 mm Slightly more than 95 mm 95 mm ANSWER DOWNLOAD EXAMIANS APP
Theory of Machine A spring controlled governor is found unstable. It can be made stable by Increasing the spring stiffness Decreasing the spring stiffness Increasing the ball mass Decreasing the ball mass Increasing the spring stiffness Decreasing the spring stiffness Increasing the ball mass Decreasing the ball mass ANSWER DOWNLOAD EXAMIANS APP
