Wheel and Axle

  • Location
Lowes: 6200 Long Prairie Road Flower Mound, TX


  • What it does
The wheel and axle rotates in a circle when you push the handle, so the machine reduces force and makes the task easier. Since it tools it will reduce force because you don't have to drag it.

Pulleys

  • Location
Gym: 4100 Morriss Road Flower Mound, TX


  • What it does
The pulley is fixed to support the weights so you can lift them. It reduces force because lifting a weight with 3 people can be the same as lifting it with 2 pulleys and one person pulling it. It seems easier but you are doing the same amount of work.

Wedge

Lowes: 6200 Long Prairie Road Flower Mound, TX


  • What it does
When a piece of wood isn't split into two entirely you can put force on a wedge to split the wood instead of splitting it with your bare hands.

Inclined Plane

  • Location
Middle School: Lamar Middle School 4000 Timber Creek Road, Flower Mound, TX


  • What it does
An inclined plane is used so someone who is handicapped won't have to work as hard to get somewhere higher. The longer the ramp the less force you need but the work is constant.
