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 95 mm 45 mm Slightly more than 95 mm Slightly less than 95 mm 95 mm 45 mm Slightly more than 95 mm ANSWER DOWNLOAD EXAMIANS APP
Theory of Machine The two elements of a pair are said to form a higher pair, when they Have a line or point contact when in motion Have a surface contact when in motion Are kept in contact by the action of external forces, when in motion Permit relative motion Have a line or point contact when in motion Have a surface contact when in motion Are kept in contact by the action of external forces, when in motion Permit relative motion ANSWER DOWNLOAD EXAMIANS APP
