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?
Simple Machines Outline Notes Pages There are 6 basic kinds of simple machines: the inclined plane, the wedge, the screw, the lever, the wheel.
Chapter 11 work and machines. Anytime that you exert a force and cause an object to move in the direction of the applied force you do _________. work.
Chapter 15 Machines What is a simple machine? People use machines to make work easier They allow a person to -change the size of the force -change.
What is mechanical advantage? The force you apply to a machine is called the effort force (input force) The force that the machine applies is the resistance.
