Machines and Mechanical Advantage Flashcard Retake

Front

What is the formula for calculating work done?

Back

Work done (W) = Force (F) × Distance (d) in the same direction.

Front

What is the unit of work in the International System of Units (SI)?

Back

Joule (J)

Front

Define mechanical advantage.

Back

Mechanical advantage is the ratio of the output force produced by a machine to the input force applied.

Front

What is the formula for calculating mechanical advantage in a lever?

Back

Mechanical Advantage = Length of effort arm / Length of load arm.

Front

What does the term 'pitch' refer to in the context of screws?

Back

Pitch is the distance between the threads on a screw.

Front

How can you increase the mechanical advantage of a lever?

Back

By moving the fulcrum closer to the load.

Front

What is the mechanical advantage of a pulley system with 2 ropes supporting the load?

Back

Mechanical Advantage = 2.

Front

What is the ideal mechanical advantage of a wheel and axle?

Back

Ideal Mechanical Advantage = Wheel radius / Axle radius.

Front

What is the relationship between force, distance, and work done?

Back

Work is done when a force moves an object over a distance.

Front

What is the significance of the fulcrum in a lever system?

Back

The fulcrum is the pivot point around which the lever rotates.
