Simple Machines Foldable Activities

Inclined plane What is the efficiency of the inclined plane?

Gears What is the IMA of the gear system when effort is placed on the large wheel? What is the IMA of the gear system when effort is placed on the small wheel?

Pulley What is the AMA of the block and tackle?

Lever What is the IMA of the catapult?

BONUS Question Inclined plane What would be the efficiency if you doubled the length of your ramp?

BONUS Question Gears How many times does the small gear need to be rotated in order for all 3 gears to end up in their starting position? (you will not need to show 3 steps) 12 36 24

BONUS Question If the Fr moved .5 meters, what is the work input? Pulley If the Fr moved .5 meters, what is the work input?

BONUS Question Lever If the work input = 50 j, what is the effort force?
