6. Mechanical Advantage- Pulley MA = count the # of “supporting ropes”

7. Now show me what you have learned!

8. What is the mechanical advantage of the pulley A, B, and C ? E E E AB C MA = 3 MA = 4 MA = 3

9. Mechanical Advantage- Lever MA = distance of the EFFORT arm distance of the RESISTANCE arm MA = Output Force (Newtons)___ Input Force (Newtons) Effort arm = INPUT FORCE Resistance arm = OUTPUT FORCE

10. What is the mechanical advantage of the lever below? 2 cm4 cm A. 8B. 0.5 C. 2D. 4 MA = distance of the EFFORT arm distance of the RESISTANCE arm

11. What is the mechanical advantage of the lever below? 5 cm 10 cm A. 5B. 0.5 C. 2 D. 50 MA = distance of the EFFORT arm distance of the RESISTANCE arm
