PPT-SIMPLE MACHINES - LEVER 1

2 SIMPLE MACHINES LEVER A lever is a rigid bar that rotates around a fixed point called the fulcrum The bar may be either straight or curved In use a lever has both an effort or applied force and a load resistant force . Tried to take a super heavy object up a flight of stairs ? WHAT HAPPENED. Example. Have you ever . Tried to cut a cake with out a knife?. Example. Have you ever . tried to unscrew a nut, bolt, or screw from something with your bare hands and discovered that it was just too tight to loosen even if you had a good grip? .

A simple machine has few or no moving parts.. Simple Machines. A simple machine has few or no moving parts.. Simple machines make work easier.. With or without a simple machine the work is the same.. Also when simple machines are combined they can make complicated bigger machines.. The Bicycle Brake. By: . Drishti. . Lakhi. Drafting. B-Day. Period 1. What is a Lever?. A . lever.  is a simple machine that makes work easier for . us.. It . involves moving a load around a . pivot, or . Machines. Lesson 7. A compound machine is a machine made of two or more simple machines. The complexity can range from being very simple to very complex. . Domestic . Machines. A . common example of a domestic compound machine is nail clippers. A nail clipper contains two levers. A second class lever and a third class lever. The cutting blades themselves are also simple machines as they are inclined planes. . .. Door Serena, Josien, Anne-Britt en Marieke. Inleiding. Uitleg over de lever.

Please write the page number in your book that supports your explanation.. Use the index of your book to help you. . Check Homework . Chapter 14 Day 5. Lesson 2. Screw, Wedge, Lever. SPI 0707.11.1 . Physical Systems: Simple Machines. Simple Machines. A simple machine is a device, composed of only one or two parts, that requires a single force to work.. The stapler works by applying a single downward force at its open end. . Why do we use machines?. Machines make doing work easier.. But they do not decrease the work that you do.. Instead, they . change the way you do work.. In general you trade more force for less distance or less force for more distance. Pay attention. Simple Machines. Simple machines assist us in doing work by creating a mechanical advantage.. They . do not . change the amount of work; they lower the effort force. There are 6 types of simple machines: lever, inclined plane, pulley, wedge, screw, and wheel and axle.. What is a machine?. A machine is simply a device that makes doing work easier. . Even a sloping surface can be a machine. . Using Machines. Mechanical Advantage. Even though machines make work easier, they don’t decrease the amount of work you need to do. . 2.1 Lever systems, examples of their use in activity and the mechanical advantage they provide in movement.
