Student Exploration Pulley Lab Answer Key [cracked] -

A pulley system has an actual MA of 3.5 and an ideal MA of 4. If you lift a 140 N load, what is the actual effort force? A: Actual MA = Load ÷ Actual Effort → 3.5 = 140 N ÷ Effort → Effort = 140 ÷ 3.5 = 40 N

If you pull the rope 2 meters, how high does the load rise? A4: 2 meters (no distance trade-off) student exploration pulley lab answer key

If the load is 50 N, what effort force is required? A3: 50 N (MA = 1 → Effort = Load/1 = 50 N) A pulley system has an actual MA of 3
