Mechanical Advantage
Mechanical advantage (MA) is a measure of how much a machine multiplies the force you put into it (input force). It's calculated by:
* MA = Output Force / Input Force
In your scenario:
* Input Force = 3 N
* Output Force = 3 N
Calculation:
* MA = 3 N / 3 N = 1
Interpretation:
A mechanical advantage of 1 means the pulley is not multiplying the force. In this case, the pulley is simply changing the direction of the force, not increasing its magnitude. This is typical for a single, fixed pulley.
Important Note: If the output force were greater than the input force (e.g., 6 N output, 3 N input), the mechanical advantage would be greater than 1, indicating that the pulley is amplifying the force.
