Real World Simple Machines
By“your name”
![Page 2: Real World Simple Machines By “your name”. Lever rigid object and a fulcrum (or pivot) Applying a force to one end of the rigid object causes it to pivot.](https://reader036.fdocuments.us/reader036/viewer/2022082713/5697bfea1a28abf838cb7537/html5/thumbnails/2.jpg)
Lever
• rigid object and a fulcrum (or pivot)
• Applying a force to one end of the rigid object causes it to pivot about the fulcrum.
• Magnifies of the force at another point along the rigid object.

Wheel & Axle
• circular device that is attached to a rigid bar in its center.
• force applied to the wheel causes the axle to rotate, which can be used to magnify the force – For example, having a rope
wind around the axle.
• force applied to provide rotation on the axle translates into rotation of the wheel– A lever that rotates around a
center fulcrum…

Inclined Plane
• a plane surface set at an angle to another surface.
• do the same amount of work by applying the force over a longer distance.

Wedge
• a double-inclined plane that moves to exert a force along the lengths of the sides.
• The force is perpendicular to the inclined surfaces, so it pushes two objects (or pieces of a single object) apart.

Screw
• a shaft that has a in inclined groove along its surface.
• rotate the screw– the force is applied
perpendicular to the groove, thus translating a rotational force into a linear one.

Pulley
• a wheel with a groove along its edge, where a rope or cable can be placed.
• applies force over a longer distance, and also the tension in the rope or cable, to reduce the magnitude of the necessary force.
