Mechanical advantage is the amount the ____ is increased.

What is force?

M. A. = Z input ÷ Z output Z is __________.

What is Distance?

This is the weight of the object being moved.

What is Output Force?

Name 2 of 3 machines that have mechanical advantages < 1.

What is Third Class Lever, Fixed Pulley or turning the axle of a Wheel & Axle?

M. A. = 10 F input = 10 N F output = ___ N

What is 100?

Two types of Pulleys.

What is Fixed & Moveable?

A Fixed Pulley has a M. A. of _____ and changes the ________ of the motion.

What is one (1) & direction?

The example of a pulley system.

What is a Block & Tackle?

F input = 10 N F output = 40 N # of ropes supporting the weight.

What is 4?

With six (6) supports ropes, you pull twelve (12m) meters of rope. The object will move_____ meters.

What is 2?

The input distance on an Inclined Plane.

What is the Length?

The output distance on an Inclined Plane.

What is the Height?

Without rollers a ramp has a great deal of _______ friction.

What is sliding ?

Length = 10 meters Height = 2 meters Object weighs = 500 N You will need to push with this amount of force.

What is 100 N?

You can only lift 100 lbs.; to lift a 600 pound object 2 meters high, you need a ramp ____ meters long.

What is 12 meters ?

Wheel Barrow, Nut Cracker, & Bottle Opener

What is a Second Class Lever?

Claw Hammer, Crow Bar & See Saw

What is a First Class Lever?

A Third Class Lever has a Mechanical Advantage of: = equal to, greater than One (1)

What is < Less than One ?

Most of the muscles on your body are set up as ____ Class Levers.

What is 3rd?

All levers have this pivot point.

What is a Fulcrum?

The 3 things Gears can change.

What is Force, Speed (Distance) or Direction?

A bolt has a radius of 2cm demands 2400 pounds of force to turn. You can only push with 100 pounds of force. You need a wrench ____ cm long.

What is 48 cm?

You turn the Axle of a Wheel and Axle. Your Input Distance will (less, more or the same) as the Output Distance.

What is Less?

When you shift gears on your bicycle, these gears require more force.

What are the higher gears ?

To increase your Mechanical Advantage, increase the radius of this.

What is the Wheel?
