More on the lever
Misc.
100
This simple machine either magnifies force or motion and consists of a bar, fulcrum, effort and resistance.
What is a lever?
100
This is the formula for finding the mechanical advantage of a lever.
What is Distance from fulcrum to effort divided by distance from fulcrum to resistance?
100
This is motivated by curiosity and the purpose is to understand why.
What is science?
100
In this class of lever the fulcrum is positioned between the effort and the resistance.
What is a first class lever?
100
This is the length of a straight line that travels from one side of a circle to another and passes through the center of the circle.
What is diameter?
200
This simple machine consists of a wheel that is attached to a cylinder.
What is a wheel and axle?
200
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?
200
The experiments done are aimed at trying to find something useful.
What is Applied Science?
200
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?
200
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?
300
This simple machine consists of a grooved wheel that rotates freely on a frame.
What is a pulley?
300
This is the formula for finding the mechanical advantage of a pulley.
What is the number of pulleys used?
300
A new process or machine that makes life better or makes a job easier.
What is technology?
300
In this class of lever the fulcrum is at one end and the resistance is between the fulcrum and the effort.
What is a second class lever?
300
This is the term used when multiple pulleys are used.
What is a block and tackle?
400
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?
400
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?
400
A device that either multiplies or redirects force.
What is a simple machine?
400
In a lever this is the term used to describe the force being applied to the lever.
What is the effort?
400
This is the equation for finding the circumference of a circle.
What is 3.14 times diameter?
500
This simple machine looks like an inclined plane but is generally used to separate things.
What is a wedge?
500
This is the formula for finding the mechanical advantage of a screw.
What is circumference divided by pitch?
500
This is a push or pull exerted on an object in an effort to change that objects velocity.
What is force?
500
In a lever this is the term used to describe the weight being lifted.
What is the resistance?
500
These are the 6 basic kinds of simple machines we have studied.
