A musculoskeletal lever system has an effort arm of 4 cm and a resistance arm of 20 cm. What is the mechanical advantage (MA) of this system, and what does it imply?

MA = 5; muscle force required is less than the resistance load MA = 0.2; muscle force required is greater than the resistance load, but movement speed at the distal end is amplified MA = 1.6; muscle force and resistance load are balanced equally MA = 80; the system operates as a second-class lever

Correct Answer:

MA = 0.2; muscle force required is greater than the resistance load, but movement speed at the distal end is amplified
