Types of Simple Machines
This simple machine either magnifies force or motion and consists of a bar, fulcrum, effort and resistance.
What is a lever?
This is the formula for finding the mechanical advantage of a lever.
What is the distance from the fulcrum to effort divided by distance from fulcrum to resistance?
This is motivated by curiosity and the purpose is to understand why.
What is science?
In this class of lever the fulcrum is positioned between the effort and the resistance.
What is a first class lever?
This is the length of a straight line that travels from one side of a circle to another and passes through the center of a circle.
What is diameter?
This simple machine consists of a wheel that is attached to a cylinder.
What is a wheel and axle?
This is the formula for finding the mechanical advantage of a wheel and axle.
What is diameter of the wheel divided by diameter of the axle?
The experiments done are aimed at trying to find something useful.
What is applied science?
In this class of lever the fulcrum is at one end and the effort is between the resistance and the fulcrum.
What is a third class lever?
If you turn the wheel in a wheel and axle the force is magnified. This is magnified if you turn the axle.
What is speed?
This simple machine consists of a grooved wheel that rotates freely on a frame.
What is a pulley?
This is the formula for finding the mechanical advantage of a pulley.
What is the number of pulleys used?
A new process or machine that makes life better or makes a job easier.
What is technology?
In this class of lever the fulcrum is at one end and the resistance is between the fulcrum and the effort.
What is second class lever?
This is the term used when multiple pulleys are used.
What is a block and tackle?
This simple machine is also known as a ramp. It is a flat supporting surface tilted at an angle with one end higher than the other and is used for raising a load.
What is an inclined plane?
This is the formula for finding the mechanical advantage of the inclined plane and a wedge.
What is length of the slope divided by height?
A device that either multiplies or redirects force.
What is a simple machine?
What is the effort?
This is the equation for finding the circumference of a circle.
What is pi (3.14) times diameter?
This simple machine looks like an inclined plane, but is used to separate things.
What is a wedge?
This is the formula for finding the mechanical advantage of a screw.
What is circumference divided by pitch?
This is a push or pull exerted on an object in an effort to change that object's velocity.
What is force?
In a lever this is the term used to describe the weight being lifted.
What is the resistance?
These are the 6 basic kinds of simple machines.
What are the lever, wheel and axle, pulley, inclined plane, wedge, and screw?
