Fluid Power

What principle states that a change in pressure at any point in a fluid is transmitted equally and unchanged in all directions throughout the fluid?

• Newton's Third Law

• Pascal's Principle

• Bernoulli's Principle

• Archimedes' Principle

What is a hydraulic system?

• A mechanical system that uses gears to transmit power.

• A device that uses pressurized gas acting on pistons of different sizes to change a force.

• A device that uses pressurized fluid acting on pistons of different sizes to change a force.

• An electrical system that uses wires and currents to operate machines.

What is the typical operating pressure range for most pneumatic systems?

• About 500 psi

• About 2000 psi

• About 100 psi or less

• About 1000 psi

Why are pneumatic components generally made of lighter materials compared to hydraulic components?

• Because pneumatic systems operate at much higher pressures

• Because pneumatic systems operate at much lower pressures

• Because pneumatic systems require electrical power

• Because pneumatic systems are only used in heavy industrial equipment

What is the largest sector for pneumatics technology?

• Residential construction

• Aerospace engineering

• Factory automation

• Automotive manufacturing

What advantage does pneumatics have over electromechanical power transmission methods?

• Heat generation is a major concern with pneumatic motors.

• Pneumatic components require bulky and expensive explosion-proof enclosures.

• Pneumatic motors will overheat and burn out if overloaded.

• Pneumatic components require no electricity, eliminating the need for heavy enclosures.
