Gears and levers

?
What is an example of a simple machine?
Lever
1 of 7
Describe levers
These increase the distance between the pivot and effort because moment=forcexdistance from pivot, The reduces the size of the force required to cause a rotation
2 of 7
What is an example of a lever?
Hammer pulling a nail out
3 of 7
What is the equation for mechanical advantage (using load and effort)?
mechanical advantage = load/effort
4 of 7
Describe gears
Adjacent gears move in opposite directions
5 of 7
What is the equation for mechanical advantage (using driven and driver gears)?
mechanical advantage = diameter of driven gear/diameter of driver gear
6 of 7
What is the equation for mechanical advantage (using number of teeth)?
mechanical advantage = number of teeth on driven gear/number of teeth on the driver gear
