Simple Machines Notes.
A simple machine is a device that helps reduce the amount of force required to do work. Work is done when a force (effort force) is applied over a distance.
Work and Simple Machines. Work Work means to (1) apply a force to an object over a distance, and (2) the object moves in response to the force. If something.

Simple Machines Inclined Plane Family Lever Family

Lever Family Simple Lever Pulley Wheel & Axle

Levers All have a rigid arm that moves on a fulcrum Wheel barrel Teeter-totter

K’NEX Hammer Increased di causes increased Fo

K’NEX Nut Cracker Increased di causes increased Fo

K’NEX Scale Balance

Pulley A modified lever that uses a wheel instead of a fulcrum Block & Tackle Multiple pulleys put together as a single unit Ex. Garage doors

Wheel & Axel A pulley (wheel) connected to a shaft (axle) Steering wheel Bigger = easier Screwdriver handle Thicker = easier

Inclined Plane Family Simple Inclined Plane Wedge Screw

Simple Inclined Plane Changes magnitude & direction of the force Ramp Decreases Finput Increases dinput

Wedge Two modified incline planes, back-to-back Blade Splitting wedge 1 downward force Turns into 2 outward forces Blade Splitting wedge Nail

Screw An inclined plane wrapped around a cylinder Screws Jar lids Spiral staircase

Compound Machine A machine that combines 2 or more simple machines Scissors Handles 2 levers joined at a common fulcrum Blades 2 wedges,
