This occurs because in a moveable pulley one end of the rope is stationary, which means it absorbs some of the force needed to move the object. The clever trick to finding the mechanical advantage of a compound pulley is by understanding the relationship between the forces acting on the pulley system. Explanation: A frictionless pulley with three support ropes carries equal tension on each of the ropes thus; Tension in each pulley rope = T. 1. In this case, the load force is the weight of the box, which is equal to its mass multiplied by the acceleration due to gravity (9. What is Pulley system? We can employ pulley systems to provide ourselves a mechanical advantage by multiplying our input effort to apply more force to a load. To lift an object weighing 1200 Newtons using a pulley with a mechanical advantage of 6, a force of 200 Newtons needs to be applied to the rope. This means that a moveable pulley will halve the required force needed to move any object attached to it. Log in Join for free. Mechanical advantage is a measure of the force amplification achieved by a Mechanical advantage actually uses the amplification in the force which we can achieve by using a device or a complete mechanical system. The mechanical advantage of a pulley system is a measure of how much the applied force is amplified. In a two pulley system the MA is 2. In this particular situation, both the output and input forces are 3 N. One important factor in determining the mechanical advantage of a pulley system is the number of ropes or pulleys used.
