INTRO TO SIMPLE MACHINES
A simple machine is a mechanical device that changes the direction or magnitude of a force.
WEDGE
A wedge is a triangular shaped tool used to separate two objects or portions of an object, lift up an object, or hold an object in place.
A wedge is a triangular shaped tool used to separate two objects or portions of an object, lift up an object, or hold an object in place.
LEVER
A wedge is a triangular shaped tool used to separate two objects or portions of an object, lift up an object, or hold an object in place.
A lever is a machine consisting of a beam or rigid rod pivoted at a fixed hinge, or fulcrum.
WHEEL & AXLE
A wedge is a triangular shaped tool used to separate two objects or portions of an object, lift up an object, or hold an object in place.
The wheel and axle consists of a wheel attached to a smaller axle so that these two parts rotate together in which a force is transferred from one to the other.
INCLINED PLANE
A wedge is a triangular shaped tool used to separate two objects or portions of an object, lift up an object, or hold an object in place.
An inclined plane is a flat supporting surface tilted at an angle, with one end higher than the other, used as an aid for raising or lowering a load.
PULLEY
A wedge is a triangular shaped tool used to separate two objects or portions of an object, lift up an object, or hold an object in place.
A pulley is a wheel on an axle or shaft that is designed to support movement and change of direction of a taut cable, rope or belt along its circumference.
SCREW
A wedge is a triangular shaped tool used to separate two objects or portions of an object, lift up an object, or hold an object in place.
A screw is a mechanism that converts rotational motion to linear motion, and a torque to a linear force.
