What is a simple machine?

Back

A simple machine is a mechanical device that changes the direction or magnitude of a force.

Front

Name the six types of simple machines.

Back

lever, pulley, wheel and axle, inclined plane, wedge, screw

Front

Define mechanical advantage.

Back

Mechanical advantage is a measure of the force amplification achieved by using a tool, mechanical device, or machine system. It is calculated by dividing the output force by the input force.

Front

How is mechanical advantage calculated?

Back

Mechanical Advantage = Output Force / Input Force

Front

Explain the concept of energy transfer.

Back

Energy transfer involves the conversion of energy from one form to another or the movement of energy from one object to another.

Front

Give an example of energy transfer in a mechanical system.

Back

Pushing a swing

Front

What are power systems in the context of engineering?

Back

Power systems in engineering refer to the network of electrical components used to generate, transmit, and distribute electricity.

Front

How is power calculated in a mechanical system?

Back

Power = Force x Distance / Time

Front

Describe the components of a mechanical system.

Back

Gears, levers, pulleys, springs, shafts

Front

What is the Engineering Design Process?

Back

A series of steps that engineers follow to come up with a solution to a problem.
