1.wheel and axle b. Screwdrivers A wheel and axle arrangement is a modified lever of the first class. It is also a simple machine in which a large wheel rotates around the centre or axle. Screwdriver is an example. 2. Wedge d.Razors A wedge is an object with at least one slanting side ending in a sharp edge. The sharp edge is used to cut materials. A wedge consists of two inclined planes. Razor is an example of a wedge. 3. Fixed pulleys e. Flagpoles In a fixed pulley, the pulley is attached to a hook or wall, and it doesn’t move. Fixed pulleys change the direction of the force applied, but do not increase the magnitude. Example: flagpoles. 4. Second class lever a. Wheel Barrows In the second class lever, the load is in between the fulcrum and the effort. Examples are a bottle opener, nutcracker and wheelbarrow. 5. Inclined plane c. Sloping roads Inclined plane helps to move heavier objects to a height. Wheelchairs and sloping roads are examples. Column A Column B 1.wheel and axle b. Screwdrivers 2. Wedge d.Razors 3.
