Simple Machines-Mechanical Advantage Theory

The closer the treads the less force and more turns needed to work. This is the mechanical advantage of a:

• Lever

• Inclined Plane

• Screw

• Wheel & Axle

• Pulley

The longer, thinner and sharper it is, the more work it does with little effort. If it's shorter and has a wider angle at the tip, one needs more force to do the work. This is the mechanical advantage of a:

• Lever

• Inclined Plane

• Wedge

• Wheel & Axle

• Pulley

If the slope is gentle, a person has to push or pull the object over a longer distance, but with little effort. If the slope is steep, a person has to push or pull the object over a very short distance, but with more effort. This is the mechanical advantage of a:

• Lever

• Inclined Plane

• Wedge

• Wheel & Axle

• Pulley

The mechanical advantage is more if the Load is closer to the fulcrum or if the effort is closer to the load. This is the mechanical advantage of a:

• Lever

• Inclined Plane

• Wedge

• Wheel & Axle

• Pulley

If force is applied to the wheel, it spins and multiplies the effort to make the output force of the axle greater. Whereas, if force is applied to the axle, it multiply the force to the wheel and result in a greater distance covered. This is the mechanical advantage of a:

• Lever

• Inclined Plane

• Wedge

• Wheel & Axle

• Pulley

The force in a fixed is equal to the lifted weight whereas in a movable the force is twice the lifted weight. This is the mechanical advantage of a:

• Lever

• Inclined Plane

• Wedge

• Wheel & Axle

• Pulley
