Answer 1

Explanation:

Type of Joint	Used to connect
Oldham's coupling	Parallel shafts with a slight offset
Universal Joint	Coplanar, Intersecting shafts
Worm and wheel	Perpendicular shafts
Belt and Pulley	Parallel shafts at a reasonable distance
Revolute joint	To transmit rotary motion

Universal Joint:

It is also called Hook's joint.
It is designed to transmit rotating motion to coplanar, non-parallel intersecting shafts.
In an automobile power from the gearbox to the rear axle is transmitted with the help of the universal joints.

Additional Information

Oldham Coupling:

It is designed to transmit the power between two parallel axis shafts at a very small distance apart from each other and is not aligned (slight offset).
The shafts connected by the coupling rotate at the same speed.
The shafts have flanges at the ends, in which slots are cut & shafts are coupled using discs.
The small variation between the shafts axis is permissible in this coupling.

Maximum sliding speed = (Distance the axes of the shafts) × (Angular velocity of each shaft)

Revolute Joint:

A revolute joint is often called a pin joint.
It is used to transmit rotational motion between two links.
A revolute pair has one degree of freedom and permits a rotational motion about an axis.
Lathe spindle in the headstock is connected with revolute joint
