In machine design one often needs to incorporate a Power Transmission between an energy source and the desired output motion. Examples of Power Transmission elements include: gears, friction drives, timing belts, flat belts, levers, and screw drives. The Power Transmission often includes a Gear Ratio or Mechanical Advantage.
WebIn physics and engineering, mechanical advantage (MA) is the factor by which a machine multiplies the force put into it. The mechanical advantage can be calculated for the following simple machines by using the following formulas: Lever: MA = length of effort arm ÷ length of resistance arm. WebThe Actual Mechanical Advantage (AMA) is the ratio of the force applied during turning of the screw head to the force exerted by the device on the material, in which it is to be inserted. Thus, this type of mechanical …
