PPT-Lever, Wheel and Axle, and Pulley

Simple Machines Simple Machines The Six Simple Machines Mechanisms that manipulate force and distance Lever Wheel and Axle Pulley Inclined Plane Screw Wedge Lever A rigid bar used to exert a pressure or sustain a weight at one point via an applied force at a second point and turning on a fulcrum at a third point. Objectives:. 1) know how six different simple machines are used in every day life to make work easier. 2) be able to calculate the mechanical advantage, and efficiency of machines.. 2.

A Push or a Pull. The Wheel and Axle. The Big Idea of this Investigation. A simple machine is a mechanical device that makes work easier by magnifying, modifying, transferring, or changing the direction of applied force. Simple machines are the elementary "building blocks" of which all complicated machines are made.. Inclined Plane. Screw. Wheel and Axle. Lever. Pulley. MACHINES. WHY?. Simple machines are useful because they can make a physical job easier by changing the magnitude or the direction of the force exerted to do work. . Ancient, Classical and Dark Ages .
