Topic 1 - Levers & Inclined Planes
This type of lever has the load in the middle.
What is a Class 2 lever?
This gear is found at the beginning of a gear train.
What is the driver?
This is known as the energy of motion.
What is kinetic energy?
Pressure is measured in these units.
What are pascals?
This is a simple machine that does one task as part of a larger, complex machine.
What is a subsystem?
This is the distance from the fulcrum to the effort in a lever.
What is the effort arm?
Gears that are connected by a chain and sprocket turn like this.
This type of energy is often referred to as the energy of position.
What is potential energy?
The formula for pressure.
What is: P = F/A ?
Multiple subsystems working together make up this.
What is a system or complex machine?
A class 3 lever gives this type of advantage.
What is a speed advantage?
These two different types of pulleys are based on the position of the wheel.
What is a fixed and moveable pulley?
The formula: E = out/in x 100 is used to calculate this.
What is efficiency?
A water jet is an example of this type of system.
What is hydraulics?
The internal combustion engine was preceded by this.
This is the formula used to calculate work.
What is: W = F x d ?
This type of simple machine can provide either a force advantage or a speed advantage.
What is a wheel and axle?
Machines can never be 100% efficient because of this.
What is friction?
Pneumatics is the study of this.
What is pressure in gases?
A complex machine designed to do a simple task (and is sometimes slightly ridiculous).
What is a Rube Goldberg machine?
A machine making a task 5 times easier is an example of this.
What is mechanical advantage?
This formula is used to calculate the speed ratio of gears.
What is: SR = driver/follower ?
The water cycle is an example of this type of energy.
Pressure transmitted equally in a closed system is known as this.
What is Pascal's Law?
What is industrialization?
