Answer:
Step-by-step explanation:
Here's how we can group the basic simple machines based on their functions:
Force Multiplier: These machines help in multiplying the force applied to them.
Lever: A lever is a simple machine consisting of a rigid bar or beam that pivots at a fixed point called a fulcrum. It allows a small force to be applied over a greater distance to move a heavy object.
Pulley: A pulley is a simple machine consisting of a wheel with a grooved rim and a rope or cable that runs along the groove. It allows a small force to be applied to lift or move a heavy object by changing the direction of the force.
Inclined Plane: An inclined plane is a sloping surface that reduces the force required to lift an object by increasing the distance over which the force must be applied.
Speed Multiplier: These machines help in increasing the speed of an object.
Wheel and Axle: A wheel and axle is a simple machine consisting of a wheel attached to an axle or shaft. It allows a small force to be applied to the rim of the wheel to rotate the axle and increase the speed of the object.
Gear: A gear is a simple machine consisting of two or more wheels with teeth that mesh together. It allows a small force to be applied to the teeth of one gear to rotate the other gear and increase the speed of the object.
Direction Changer: These machines help in changing the direction of an applied force.
Pulley: A pulley also falls under this category, as it allows the direction of the applied force to be changed.
Inclined Plane: An inclined plane also falls under this category, as it allows the direction of the applied force to be changed when lifting or moving an object.
