A crank of slider crank mechanism rotates clock wise at

constant speed of 300 rpm. The crank is 150 mm and

connecting rod is 600 mm long.

Determine:

(i) Linear velocity of the midpoint of connecting rod.

(ii) Angular acceleration of connecting rod at a crank angle

of 45° from inner dead centre position.

(i) Linear velocity of the midpoint of connecting rod :
