Simple Machines
"Simple Machines (Guess by Image)" is an activity or educational exercise where participants are shown pictures of various simple machines, such as levers, pulleys, inclined planes, screws, wheels and axles, or wedges. Based on the image, they are asked to identify which type of simple machine is depicted. This approach helps learners visually recognize and understand the basic mechanical devices that make work easier by changing force or motion.

❓ Frequently Asked Questions
What is a simple machine?
A device that changes the size or direction of a force to make work easier, using mechanical advantage.
What are the six classic simple machines?
Lever, inclined plane, wheel and axle, pulley, screw, and wedge.
What does mechanical advantage mean in simple machines?
It’s the factor by which a machine multiplies your input force, letting you move a load with less effort.
Can you name everyday examples of simple machines?
Ramp (inclined plane), door wedge (wedge), bottle cap or screw-cap (screw), crowbar (lever), window blinds (pulley), and a wheelbarrow (wheel and axle).
