SIMPLE MACHINE
Welcome to class! Teacher: Master Segun. In today’s class, we will be talking about the simple machine. Enjoy the class! The development of simple machines is fascinating helpful because we use them in our everyday life. They make our work easier and faster. A difficult work can be executed without much stress, e.g. lifting of heavy objects, pushing or pulling heavy objects, etc. A simple machine is an essential mechanical device/tool which allows force (effort) applied at one point to overcome a resistance force (load) at the other end. Generally, a machine enables us to overcome a large resistance or load by applying a small effort or force. Working with a simple machine makes it more convenient than it could be done without it. DEFINITION OF TERMS USED IN SIMPLE MACHINE 1. Mechanical Advantage (M.A): This is the ability of a machine to overcome a large load/resistance through a small effort. It is the ratio of load to effort applied and it is unitless. 2. Velocity Ratio (V.R): This
