Step 1: Calculate the load (L). The load is the weight of the 10 kg mass. L = m × g L = 10 kg × 10 m/s^2 L = 100 N Step 2: Determine the Velocity Ratio (VR) of the pulley system. The velocity ratio for a block and tackle system is equal to the number of rope segments supporting the movable block. In this diagram, there are 6 segments of rope supporting the lower block (which carries the load). VR = 6 Step 3: Calculate the Mechanical Advantage (MA). Mechanical advantage is the ratio of the load to the effort. MA = LoadEffort MA = 100 N70 N MA = (10)/(7) Step 4: Calculate the efficiency () of the machine. Efficiency is the ratio of mechanical advantage to velocity ratio, expressed as a percentage. = (MA)/(VR) × 100\% = (10)/(7)6 × 100\% = (10)/(7 × 6) × 100\% = (10)/(42) × 100\% = (5)/(21) × 100\% ≈ 0.238095 × 100\% ≈ 23.81% Send me the next one 📸
