Hydraulic Jack

What is the working principle of a hydraulic jack?

• Newton's principle

• Boyle's law

• Pascal's principle

• Archimedes' principle

Name three components of a hydraulic jack.

• gear

• screw

• cylinder, pump, hydraulic fluid

• pipe

Provide two applications of hydraulic jacks.

• Cooking food in restaurants

• Playing music in concerts

• 1. Lifting vehicles for tire changes or repairs in automotive repair shops. 2. Lifting heavy loads or structures for construction purposes.

• Watering plants in gardens

What are the advantages of using a hydraulic jack?

• Hydraulic jacks are prone to leaking fluid

• Hydraulic jacks are difficult to operate

• Hydraulic jacks are not suitable for heavy lifting

• Hydraulic jacks offer higher lifting capacity, ease of use, stability, and durability.

Mention two disadvantages of hydraulic jacks.

• Size and weight, regular maintenance needed

• Noisy operation, limited lifting capacity

• Difficult to transport, expensive to purchase

• Slow operation, risk of hydraulic fluid leaks

How does a hydraulic jack work to lift heavy objects?

• A hydraulic jack uses oil to transfer force and lift heavy objects.

• A hydraulic jack works by blowing air to lift heavy objects.

• A hydraulic jack uses electricity to lift heavy objects.

• A hydraulic jack relies on magnets to lift heavy objects.

Explain the role of hydraulic fluid in a hydraulic jack.

• Hydraulic fluid provides electrical power to the jack

• Hydraulic fluid cools down the system

• Hydraulic fluid transmits force and pressure within the hydraulic jack system.

• Hydraulic fluid lubricates the mechanical parts

Discuss the importance of seals in a hydraulic jack.

• Seals in a hydraulic jack are important for preventing leaks and maintaining pressure within the system.

• Seals in a hydraulic jack are designed to increase friction and slow down the system.

• Seals in a hydraulic jack are unnecessary and can be removed.

• Seals in a hydraulic jack are used for decorative purposes only.

Why are hydraulic jacks preferred in automotive repair shops?

• Hydraulic jacks provide high lifting capacity, are easy to use, and offer smooth and controlled lifting and lowering of vehicles.

• Hydraulic jacks are heavier and harder to transport

• Hydraulic jacks are more expensive than other types of jacks

• Hydraulic jacks require frequent maintenance and repairs

How does the mechanical advantage of a hydraulic jack help in lifting heavy loads?

• The mechanical advantage of a hydraulic jack is achieved through Pascal's principle, allowing a small input force to generate a larger output force to lift heavy loads.

• The mechanical advantage of a hydraulic jack is based on Newton's third law of motion

• The mechanical advantage of a hydraulic jack is achieved by using gears

• The mechanical advantage of a hydraulic jack is due to magnetic forces
