They are found in many objects that you encounter in your everyday life. They enable you to lift objects or they make easier to move them around.
What are simple machines?
100
It's when you pull the corners of a metal sheet in opposite directions.
What is a shearing force?
100
This transforms a circular motion into an alternating motion.
What is a cam and follower?
100
This simple machine that is composed of a movable bar that rests on a point called a fulcrum.
What is a lever?
100
These are toothed wheels that turn as they press against each other. Two of these toothed wheels turn in opposite directions to each other.
What are gears?
200
This is a long rod whose ends enter one or more wheels.
What is an axle?
200
It's when you squeeze a sponge. It's the opposite of a tension force.
What is a compression force?
200
This mechanism transforms a circular motion into a rectilinear motion.
What is a nut and screw?
200
This simple machine is composed of a circular object and a long rod that is widely used in are day-to-day life.You could drag a box along the ground.
What is the wheel and axle?
200
These are similar to gears. The difference are that they have no teeth.
What are friction wheels?
300
It can be combined with two or more simple machines.
What is a mechanical system?
300
It's when you press or pull against a bar, adding weight to the bar. The bar is likely to bend.
What is a flexion force?
300
This transforms a circular motion into an alternating motion It is used sometimes in a combustion engine.
What is a connecting rod and crank?
300
This is usually in a triangular prism. It is used to exert a force on an object. For instance, it can be used to pry two objects apart.
What is a wedge?
300
This is a mechanism that transmits rectilinear motion. Cranes use this mechanism.
What is the pulley
400
It's any interaction that, when unopposed, will change the motion of an object. In other words, it can cause an object with mass to change its velocity (which includes to begin moving from a state of rest).
What is a Force?
400
It is when you pull an object in one direction to move it.
What is a tension force?
400
This mechanism changes circular motion into rectilinear motion. It is composed of a toothed wheel that turns on a toothed bar.
What is a rack and pinion?
400
This slope reduces the force that must be exerted to lift a load or object.
What is an inclined plane?
500
It is the relationship between the force required to move a load without a device, and the force needed to move the load using a machine or mechanical system.
What is a mechanical advantage?
500
This is the force that pulls objects toward the center of the Earth.
What is a gravitational force?
500
What is ____? Baby don't hurt me, don't hurt me. No more.
What is LOVE?
500
This does not reduce the force needed to preform a task. It only enables the direction of the force to be changed.
