*Pulley Systems* 🛠️ - Used to _lift loads_ with _less effort_ - Types: Fixed, Movable, Block & Tackle *Velocity Ratio (VR)* 🚀 - VR = distance effort moves / distance load moves - Example: 2-pulley system → VR = 2 *Efficiency (η)* ⚙️ - η = (load × distance load moves) / (effort × distance effort moves) - η = (Mechanical Advantage / VR) × 100% - Friction reduces η 😕 #science #waec2026 #schools #stemeducation | Simplified Science

Watch @megas_sends as he uses a block and tackle mechanical advantage (MA) system to raise the load and isolate a section of climbing rope that has been damaged with a “core shot” 🚑 So simple, yet so complex. It might just be magic. 🪄 This is one capability of keeping the ends of the cordolette untied as it can be a much more versatile tool. 🚨 WARNING: Mammut Core Protect ropes have an increased cut resistance compared to a dynamic climbing rope of the same diameter, but any rope can break in
