Question

The link, in which the motion is transmitted with the help of fluid pressure, is called the fluid link. Example for fluid link is:

• A. Piston
• B. Hydraulic brake
• C. Crank shaft
• D. Rope drive

Hint:

If the motion travels through oil or water to do work, it's a fluid link.

Answer 1

The Correct Option is B

Step 1: Concept A fluid link is a type of kinematic link where power or motion is transmitted through a fluid (liquid or gas) under pressure.

Step 2: Meaning Unlike rigid links (like a connecting rod) or flexible links (like a belt), fluid links rely on the incompressibility of liquids to move parts of a machine.

Step 3: Analysis In a hydraulic brake system, the pressure applied at the brake pedal is transmitted through brake fluid to the brake calipers, acting as a link to engage the brakes. Pistons and crankshafts are rigid links, while a rope drive is a flexible link.

Step 4: Conclusion Therefore, the hydraulic brake is a classic example of a fluid link.
Final Answer: (B)
