PARTA
Answer any three full questions, each carries 10 marks. Marks
1 Find the degrees of freedom of the following cases.

(10)
c) A planar link
2 For the position of the mechanism shown in figure, find the velocity of the
slider B for the given configuration if the velocity of the slider A is 3m/s.

3 PQRS is a four-bar chain with link PS fixed. The lengths of the links are PQ =
62.5 mm; QR = 175 mm; RS = 112.5 mm; and PS = 200 mm. The crank PQ
rotates at 10 rad/s clockwise. Draw the velocity and acceleration diagram when (10)
angle QPS = 60° and Q and R lie on the same side of PS. Find the angular
velocity and angular acceleration of link QR.
