Mechanical advantage is a measure of the ratio of output force to input force in a system, used to analyze the forces in simple machines like levers and pulleys.Despite changing the forces that are applied the conservation of energy is still true and the output energy is still equal to the input energy. Compound 9:1 systems are a piece of cake if you already know how to rig a 3:1.. This is handy if you rig a 3:1 and don't quite have enough pulling power. 9:1 requires 9 feet of rope for 1 foot of gain while adding the benefit of easier pull. 5-to-1 MA: If the 3-to-1 system is not appropriate due to haul lane length or significant heights, convert it into a compound 5-to-1 by placing an additional change-of-direction pulley at the. You just need to enter the input fields and click on the calculate button to get the mechanical average easily. Mechanical advantage is a measure of the ratio of output force to input force in a system, used to analyze the forces in simple machines like levers and pulleys. The mechanical advantage obtained is based on the pulley effect. For example, if there are four moving pulleys and 8 lines (the most left line is used only for change of direction) the MA = 8. About Press Copyright Contact us Creators Advertise Developers Terms Privacy Policy & Safety How YouTube works Test new features Press Copyright Contact us Creators . Rule #1: If the pulley closest to the haulers is on the anchor, the pulley is only considered a change of direction (cd). Example 1. 5:1 haul system. 5:1 System. Here F A is the anchor load, F E is the effort force and F L is the load. Mechanical Advantage- The primary purpose of a hauling system is to gain mechanical advantage. The formula of mechanical advantage is given as: Wherein, MA is the mechanical advantage, F B = force of the object and. F A = effort to overcome the force of the object.
