If the radius of gyration of a compound pendulum about an axis through e.g. is more, then its frequency of oscillation will be                        
A. less B. more
C. same D. data are insufficient to determine same



8.

In a darg link quick return mechanism, the shortest link is always fixed. The sum of the shortest and longest link is                        
A. equal to sum of other two B. greater than sum of other two
C. less than sum of other two D. there is no such relationship



9.

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                        
A. 95 mm B. slightly less than 95 mm
C. slightly more than 95 mm D. 45 mm




10.

In a mechanism, usually one link is fixed.If the fixed link is changed in a kinematic chain, then relative motion of other links                        
A. will remain same B. will change
C. could change or remain unaltered depending oh which link is fixed D. will not occur



11.

In above example, the minimum length of the coupler will be                        
A. 45 mm B. slightly less than 45 mm
C. slightly more than 45 mm D. 95 mm



12.

In its simplest form, a cam mechanism consists of following number of links                        
A. 1 B. 2
C. 3 D. 4
