Find the force needed to lift a 2,000 N weight using a machine with a mechanical advantage of 15.
Question
Find the force needed to lift a 2,000 N weight using a machine with a mechanical advantage of 15.
Solution
To find the force needed to lift a 2,000 N weight using a machine with a mechanical advantage of 15, we can use the formula for mechanical advantage:
Mechanical Advantage = Output Force / Input Force
In this case, the output force is the weight we want to lift (2,000 N) and the input force is the force we need to apply. We can rearrange the formula to solve for the input force:
Input Force = Output Force / Mechanical Advantage
Substituting the given values into the formula:
Input Force = 2,000 N / 15
Calculating the input force:
Input Force = 133.33 N
Therefore, the force needed to lift the 2,000 N weight using a machine with a mechanical advantage of 15 is approximately 133.33 N.
