page 2 of 2 Force and Work Apply Try This You may want to view the Simple Machines Flip Book to review the simple machines that you have been studying before continuing with the project. Play Simple Machines Transcript Now, look around you. Find two examples of each of the simple machines listed below. Make a simple sketch of each simple machine. Explain how the design of each helps to reduce the amount of force required to do work. This may be a labeled diagram or using two to three sentences for each example that you find.

Here’s a structured approach to completing your project on simple machines based on your request.

Lever

Example 1: Seesaw

Sketch: Draw a seesaw with a fulcrum in the middle and people on either side.
Explanation: The seesaw acts as a lever, where the fulcrum allows a smaller amount of force applied at one end to lift a larger load on the other. By changing the distance from the fulcrum (the pivot point), it enables one person to lift another with less effort.

Example 2: Crowbar

Sketch: Draw a crowbar being used to lift a heavy object, showing the fulcrum point.
Explanation: In this case, the crowbar functions as a lever with the fulcrum under one end. The person applies force on the long arm of the crowbar, which magnifies their effort, allowing them to lift a heavy object with less input force.

Inclined Plane

Example 1: Ramp

Sketch: Draw a ramp leading up to a door with a cart on it.
Explanation: The ramp allows objects to be rolled up to a higher elevation rather than lifted straight up. The longer slope of the ramp reduces the amount of force needed to elevate items, making it easier to move heavy objects.

Example 2: Wheelchair Ramp

Sketch: Draw a wheelchair ramp going up to a curb.
Explanation: A wheelchair ramp is a type of inclined plane that enables individuals using wheelchairs to ascend or descend safely. The gradual slope requires much less force than lifting the wheelchair vertically, making it accessible for everyone.

Pulley

Example 1: Flagpole Pulley

Sketch: Draw a flagpole with a flag being raised using a pulley.
Explanation: The flagpole pulley system utilizes one or more wheels to change the direction of the force applied. Pulling down on the rope requires less force to lift the flag upward, as the pulley helps distribute the weight.

Example 2: Crane with Pulley System

Sketch: Draw a construction crane with a load being raised by a pulley.
Explanation: A crane uses multiple pulleys to lift heavy loads. Each additional pulley in the system increases the mechanical advantage, meaning less force is needed to raise heavy materials, allowing construction workers to lift and position large objects effectively.
