Question

Given an effort force (Fe) of 25lb and a resistance force (Fr) of 175lb, calculate the Actual Mechanical Advantage (AMA). Round your answer to the nearest whole number.

Answer 1

The Actual Mechanical Advantage (AMA) is calculated as the ratio of the resistance force to the effort force, yielding an AMA of 7 when rounding to the nearest whole number.

Step-by-step explanation:

To calculate the Actual Mechanical Advantage (AMA), we use the ratio of the resistance force (Fr) to the effort force (Fe). The formula for AMA is given by AMA = Fr / Fe. Using the provided values, where the effort force is 25lb and the resistance force is 175lb, we can calculate the AMA as follows:

AMA = Fr / Fe
AMA = 175lb / 25lb
AMA = 7

Therefore, the Actual Mechanical Advantage (AMA) of this system is 7 when rounded to the nearest whole number.
