WebApr 4, 2024 · The pulley system shown in the above pulley system is a variation of the second-order pulley system. Velocity Ratio (VR) = 2 × number of movable pulleys = 6 Mechanical Advantage (MA) = η × VR MA = 0.85 × 6 MA = 5.1 MA = W/P = 5.1 P = W/51 P = 2352.94 N. The force (P) of 2352.94N is required to lift the load of 12000N. WebThe first formula for mechanical advantage is M A =2n M A = 2 n. Plugging in the correct value for the number of movable pulleys, we get the equation M A= 2(1) ⇒ M A = 2 M A = …

WebMar 16, 2024 · The mechanical advantage of a moveable pulley is 2. This means that a moveable pulley will halve the required force needed to move any object attached to it. 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. How do you calculate IMA of a … WebThe ideal mechanical advantage (IMA) of a pulley is directly dependent upon the number of support strings, N. Inclined plane. The inclined plane is a simple device that hardly looks like a machine at all. The mechanical advantage increases as the slope of the incline decreases. お手玉 イラストかわいい
