1.A simple machine is a machine 2.Also it is a tool that magnifies effort 3.And it helps and it is easier to lifted for instance a lever. Mechanical device A rigid bar pivoted about a fulcrum A simple machine that gives a mechanical advantage when given a fulcrum. To move or force, especially in a effort to get something open. A inclined Plane is a ramp that uses less effort by traveling a greater distance. Plank or other plane surface placed at an angle to a horizontal surface and used to heavy weights to a higher level with little force. It is a simple machine. Medal cylinder with a ridge twisted evenly round its length and often a groove across the head. Used to separate two objects or portions of objects through the application of force. A wheel and axle is a lever that rotates in a circle around a center point or fulcrum. The larger wheel ( or outside) rotates around the smaller wheel ( axle ). Is a mechanism composed of a wheel on an axle or shaft that may have a groove between two flanges around it’s circumference A rotating machine part having cut teeth or cogs which mesh with another toothed part in order to transmit torque A concept such as a push or pull that can cause a object with mass to change velocity. The effort needed to move a certain distance. Is the factor by which a mechanism multiplies the force or torque applied to it.
