Energy sources not derived from fossil fuels, including renewable and inexhaustible.
What is alternative energy?
A system of substations, power lines, and transformers that delivers electricity from power sources to consumers.
What is the power grid?
The type of lever where the effort force is at one end and the fulcrum at the other.
What is a second class lever?
It is made up of more than one simple machine.
What is a compound machine?
A legal document which is a log or journal that serves as an archival repository for solution ideas that are generated throughout the design process.
What is an engineering notebook?
A machine for producing power in which a rotor is made to move by a fast-moving flow of water, steam, gas or air.
What is a turbine?
This law can be written as:
Voltage = Current x Resistance
Current = Voltage / Resistance
Resistance = Voltage / Current

This is the purpose of a fixed pulley with a mechanical advantage of 1.
What is to change the direction of force?
A situation in which the total forces acting on an object at rest add up to zero.
What is static equilibrium?
