Mechanical Advantage : Inclined Plane Family

Using a lever, Joe is able to lift a 10,000 N car off of the ground with a force of 1000 N. What is the mechanical advantage of the lever?

• 1
• 10
• 100
• 1000

What is the primary mechanical advantage of using the simple machine seen in the image?

• You can apply a large force and have it penetrate over a very long distance.
• You can apply a long distance and have it convert into a very short distance.
• You can apply a short distance and have it multiplied to penetrate a large distance.
• You can apply a small force to penetrate something that normally requires a large force.

Input force is the same as 

• output
• resistance 
• effort

What is resistance (output) force?

• the force required by a machine in order to accomplish work (the force you put on the machine)

• The force that is exerted by a machine

• the force the machine exerts on a object

• the output work times the input distance

What is effort (input) force?

• the force one exerts on a machine

• the force which an effort force must overcome in order to do work on an object via a simple machine.

• the force the machine exerts on a object

• the output work times the input distance
