How does a single fixed puled, like the one seen here, help you do work?

changes the direction of the force

increases the amount of applied force

decreases the amount of applied force

allows you to pull the rope a shorter distance

The amount by which a machine multiplies input force is known as the

work.

power.

output force.

mechanical advantage.

The 3 parts of a lever are:

fulcrum, effort, and load

load, output, and input

input, effort, and fulcrum

pivot, output, and fulcrum

10.

The IMA (ideal mechanical advantage) formula for an inclined plane is:

length/height

height/length

none of these

ramp length plus ramp height

11.

Which lever makes it easier to lift a load (box)?

the 3 levers are all the same

12.

What is effort (input) force?

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

13.

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 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

14.

How can you reduce the amount of force required to lift an object using an inclined plane (ramp)?

increase the length of the ramp
