A power point presentation by Student Name.
A wheel with teeth that interlocks with another gear.
There are two kinds of gears:
You can find gears in almost anything mechanical that moves. Here are some examples:
~ Car motors and transmissions
This is the MA formula :
MA=radius of driver gear
radius of follower gear
Gears give you force or speed advantages.
~For a speed advantage,the driver gear is bigger than the follower gear.
~The formula for a speed advantage in gears is
SR= # of teeth on driver gear
# of teeth on follower gear
Bob turns a gear that has a radius of 10 cm.
If the follower gear has a radius of 5cm, what is the mechanical advantage of the two gears?
