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 minimum length of the coupler will be Slightly more than 45 mm 95 mm Slightly less than 45 mm 45 mm Slightly more than 45 mm 95 mm Slightly less than 45 mm 45 mm ANSWER DOWNLOAD EXAMIANS APP
Theory of Machine When the belt is stationary, it is subjected to some tension known as initial tension. The value of this tension is equal to the Tension in the slack side of the belt Tension in the tight side of the belt Sum of the tensions on the tight side and slack side of the belt Average tension of the tight side and slack side of the belt Tension in the slack side of the belt Tension in the tight side of the belt Sum of the tensions on the tight side and slack side of the belt Average tension of the tight side and slack side of the belt ANSWER DOWNLOAD EXAMIANS APP
