Theory of Machine The example of lower pair is

Automobile steering gear
Straight line motion mechanisms
All of these
Shaft revolving in a bearing

Theory of Machine When the belt is stationary, it is subjected to some tension known as initial tension. The value of this tension is equal to the

Tension in the slack side of the belt
Sum of the tensions on the tight side and slack side of the belt
Average tension of the tight side and slack side of the belt
Tension in the tight side of the belt

Theory of Machine A rotor which is balanced statically but not dynamically is supported on two bearings L apart and at high speed of the rotor, reaction on the left bearing is R. The right side of the bearing is shifted to a new position 2L apart from the left bearing. At the same rotor speed, dynamic reaction on the left bearing in the new arrangement will

Become equal to 2R
Become equal to R/2
Become equal to R/4
Remain same as before

Theory of Machine The Coriolis component of acceleration is taken into account for

Four bar chain mechanism
All of these
Slider crank mechanism
Quick return motion mechanism

Theory of Machine The relation l = (2/3).(j + 2) apply only to kinematic chains in which lower pairs are used. This may be used to kinematic chains in which higher pairs are used, but each higher pair may be taken as equivalent to

Two lower pairs and two additional links
One lower pair and two additional links
Any one of these
Two lower pairs and one additional link
