A universal joint is a coupling that allows a rigid rod to bend in any direction while transferring torque from one plane to another. There are several types of universal joints, including cross type, ball and trunnion type, and constant velocity type, which utilize basic mechanical principles for flexible rotation. Universal joints can be made from various materials, such as steel or plastic, depending on the application and cost requirements.

2. What is a Universal Joint? What is it’s purpose?
 A universal joint is a joint or coupling in a rigid rod
that allows the rod to 'bend' in any direction.
 The purpose of a universal joint is to transfer
torque from one plane to another, retaining
whatever rotational energy applied to the shaft.

3. Types of Universal Joints
 Cross Type or Two Yoke Type.
 Ball And Trunnion Type.
 Constant Velocity Type.

5. Design/Structure
 A universal joint uses basic mechanical principles,
there are four points of attachment (usually with
needle bearings), two per shaft.
 Each of these shaft ends (called yoke arms or yoke
ends) attaches to a cross piece, providing a flexible
joint which can take large loads.

6. Features and Functions
 As mentioned earlier the whole concept of a
universal joint is to provide a mechanical means
for transmitting torque and rotation.
 The Universal joint only suffers from one major
problem: even when the input drive shaft axle
rotates at a constant speed, the output drive shaft
axle rotates at a varying speed.

7. Materials Used
 Universal joints can be made out of almost any
material depending on the application.
 Steel, cast iron, brass or even plastic.
 Cost can effect the materials.
