1 st 2 nd amp 3 rd class Levers Give me a lever long enough and a fulcrum on which to place it and I shall move the world Archimedes Levers Gaining More Leverage 1 st class levers review. 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. What are the 6 types of . What is a Simple Machine?. A simple machine has few or no moving parts.. Simple machines make work easier. Wheels and Axles. The wheel and axle are a simple machine. The axle is a rod that goes through the wheel which allows the wheel to turn. To be able to describe the three classes of lever.. To know which levers have a mechanical advantage/disadvantage.. Levers. Levers. In order to produce movement your muscles and bones work together as a series of levers.. . DEFINATION. :A mechanical lever is a rigid bar that rotates around a axis or a fulcrum.. Rigid bar. fulcrum. Chaitali prabhudesai. Forces. The lever consist of two forces:. An effort force. : which will tend to rotate the bar around the fulcrum . 10.1 The skeletal system provides movement and protection. 10.2 The muscular system makes movement possible. 10.3 Muscles exert forces. 10.4 Bones and joints at as levers.
