🔧 Mechanical Advantage (MA) System Refresher Training for New Fire Officers 🚒 Mechanical Advantage (MA) is the force relationship between the input force (what the firefighter pulls) and the load (what is being lifted or lowered). ✅ What is 1:1 MA? A 1:1 mechanical advantage means: • No force multiplication • The force you apply equals the force on the load • If the load weighs 50 kg, you must apply 50 kg of force (minus friction) 1:1 with CD #ropetraining #ropes #mechanicaladvantage #ropetuto
