OR
Q.3 (a) Derive a relation for minimum number of teeth on gear wheel and the pinion to
avoid interference.
07
(b) By using Klein?s construction method, explain the procedure to determine
velocity and acceleration of a slider crank mechanism.
07

Q.4 (a) Explain different types of cams with neat sketches. 07
(b) Explain the effect of gyroscopic couple on Naval ship during steering, pitching
and rolling.
07
OR
Q.4 (a) Explain working of pantograph mechanism with suitable diagram. 07
(b) Draw displacement, velocity and acceleration diagram for SHM and constant
velocity motion of the follower.
07

Q.5 (a) Explain static balancing and dynamic balancing. 07

??
for a flat belt drive. 07
OR
Q.5 (a) Draw the profile of a cam operating a knife-edge follower having a lift of 30 mm.
The cam raises the follower with SHM for 1500 of the rotation followed by a
period of dwell for 600 .The follower descends for the next 1000 rotation of the
cam with uniform velocity, again followed by a dwell period. The cam rotates at
a uniform velocity of 120 rpm and has a least radius of 20 mm.
