Question

Crank is an example of which type of link:
1. Rigid link
2. Fluid link
3. Flexible link
4. Floating link

Answer 1

Correct Answer - Option 1 : Rigid link

Explanation:

Fluid Link:

• A fluid link is one that is deformed by having an incompressible fluid in a closed vessel and the motion is transmitted through the fluid by pressure, as in the case of a hydraulic press, hydraulic jack, and hydraulic brake.

Rigid Link:

• A rigid link is one that does not undergo any deformation while transmitting motion. Links in general are elastic in nature.
• They are considered rigid if they do not undergo appreciable deformation while transmitting motion, for example connecting rod, crank, tappet rod etc.

Resistant Link:

• A link that is rigid for the purposes it serves.
• Apart from rigid links, there are some semi-rigid links that are normally flexible, but under certain loading conditions act as a rigid link for limited purposes and thus are the resistant link.
• These days resistant links are usually referred to as rigid links.

Flexible Link:

• A flexible link is one which while transmitting motion is partly deformed in a manner not to affect the transmission of motion, for example, belts, ropes, chains, springs, etc.

Floating Link:

• This is a link that is not connected to the frame.
