A compound machine is a machine formed from a set of simple machines connected in series with the output force of one providing the input force to the next. For example, a bench vise consists of a lever (the vise's handle) in series with a screw, and a simple gear train consists of a number of gears ( wheels and axles ) connected in series.
The actual mechanical advantage (AMA) is the mechanical advantage determined by physical measurement of the input and output forces. Actual mechanical advantage takes into account energy loss due to deflection, friction, and wear. The AMA of a machine is calculated as the ratio of the measured force output to the measured force input,
The mechanical advantage of a simple machine as defined as the ratio of the output force exerted on the load to the input force applied. The inclined plane the output load force is just the gravitational force of the load object on the plane, its weight . The input force is the force exerted on the object, parallel to the plane, to move it up ...

A science project is an educational activity for students involving experiments or construction of models in one of the science disciplines. Students may present their science project at a science fair, so they may also call it a science fair project. Science projects may be classified into four main types.
A lever is a simple machine consisting of a beam or rigid rod pivoted at a fixed hinge, or fulcrum.A lever is a rigid body capable of rotating on a point on itself. On the basis of the locations of fulcrum, load, and effort, the lever is divided into three types.
This means the input force on the rope is F A =F B /n. Thus, the block and tackle reduces the input force by the factor n. A double tackle has two pulleys in both the fixed and moving blocks with four rope parts (n) supporting the load (F B) of 100 N. The mechanical advantage is 4, requiring a force of only 25 N to lift the load.
