This a a basic activity to demonstrate the mechanical advantage of pulleys. Students can see that a fixed pulley helps only by allowing you to pull down with gravity in order to lift an object up. Movable pulleys double the amount of line pulled and decrease the effort required to lift an object. We can calculate it by simply counting how many parts, or legs, of rope are acting on the pulley: in this case there are 2, so we calculate a 2:1 advantage. The other is attached to an anchor point. The simplest form of a block and tackle system is a 2:1 mechanical advantage setup called a Gun Tackle

Energy is conserved. Of course we have taken no account of any friction in the pulley. Some work may be required to overcome the friction so the second instance requires a bit of excess force. The mechanical advantage of the single movable pulley example is 2 since the force required to move the iron block is 1/2 its weight. The efficiency (E) of a haul system may be calculated by adding the effects of each pulley. Start by drawing a simple diagram of the system, then show the pulling force F that the hand applies to the rope. Transmit the force F along the rope by adding the effects of each pulley.

The pulleys each turn freely on a pin as axis, and are drawn with different diameters, to show the parts of the rope more clearly. There are 5 parts of rope. Note: For rope (n1, n2, etc.), the velocity which the weight W will be raised equals of the velocity of the force applied at F.

It explains the means by which a pulley can double its input force, examines common examples of both simple and compound rope and pulley MA (mechanical advantage) systems, and explains how to calculate mechanical advantage ratios in those systems.

Purpose: To determine the mechanical advantage and efficiency of a single-fixed pulley, a single-movable pulley and a block-and-tackle pulley system. Hypothesis: Pulleys are used to make work seem easier. There are two ways in which a pulley can make work easier. Pulleys can change the direction of the force aliesmal110-Your question should be more specific. First, high ratio worm gear drives typically have fairly low input-to-output efficiency, and this efficiency can vary greatly depending upon the particular system design (ie. oil or grease lubrication, rolling element vs. plain bearings, etc.) and the operating conditions at which the efficiency is being measured. Calculate the mechanical advantage of each pulley arrangement and include it in your table. If your scale is calibrated in units of weight, you can easily convert to units of force (N, Newtons) by multiplying the weight (in kg) by 9.8 m/s 2 .

That means that the tension correspond to half of the weight. So it also means that your pulling force is half the weight.Calculating Forces in the Pulley Mechanical Advantage Systems Used in Rescue Work
Therefore, the simplest way to determine mechanical advantage is in a ratio of length of pull to the displacement of the load: A = (length of pull) / (displacement of load) If your load needs to move 10 cm and you set up your pulley system so that it pulls 30 cm of string to move the load 10 cm, then you have a mechanical advantage of 3.
