PLTW intro to Mechanical Engineering

This is where power comes out of the mechanism

• Output

• Input

• Torque

• Mesh

• Teeth

This allows power or energy to transfer between gears

Speed and torque have an inverse relationship. This means...

• When one increases the other decreases

• Both increase

• Both decrease
