What is reversibility of machine explain with example?

Reversible machine : A machine which is capable of doing work in the reverse direction even after the removal of effort ,load get lifted is called Reversible machine. Non – Reversible machine : A machine which is not capable of doing work in the reverse direction is called Non – Reversible machine.

What is a reversible process give an example?

Examples of Reversible Process extension of springs. slow adiabatic compression or expansion of gases. electrolysis (with no resistance in the electrolyte) the frictionless motion of solids. slow isothermal compression or expansion of gases.

Is screw jack a reversible machine?

Screw jack is a non reversible machine,as it does not return to its original position even after the load is applied.

What is the meaning of reversible machine?

If a machine is capable of doing some work in the reversed direction, after the effort is removed, then the machine is known as reversible machine. The condition for a machine to be reversible is that its efficiency should be more than 50 \%.

Which is non-reversible machine?

A non-reversible machine is also called a self-locking machine.

What are some examples of reversible changes?

Examples of reversible changes are:

• Melting of ice.
• Boiling of water.
• Melting of wax.
• Stretching of a rubber band.
• Stretching of a spring.
• Inflation of a ballon.
• Ironing of clothes.
• Folding of paper.

Which of the following are reversible?

Melting, boiling, evaporation, freezing, condensation, and disintegration are examples of reversible transformations. Melting wax, freezing ice, and boiling water that evaporates as steam and condenses back to water are a few examples. Hence option C is correct.

What is reversible machine and self locking machine?

Reversibility of a Machine The machine is said to be self-locking if the load is not lowered on removal of the effort. A lifting machine is reversible if its efficiency is greater than 50 percent and self locking if its efficiency is less than 50 percent.

Which thread is used in screw jack?

Answer: Square thread is used in screw Jack. Explanation :- In heavy-duty applications, such as screw jacks, a square thread or buttress thread is used, because it has the lowest friction and wear.

Which of the following is reversible process?

Isothermal compression is reversible, for example, Carnot cycle, heat engine.

What is condition for reversible machine?
