Question

select the correct answer. victoria has a crate of vegetables that weighs 100 newtons. she exerts a force of 100 newtons to lift the crate with a pulley. what’s the mechanical advantage in this situation?
a. less than 1
b. equal to 1
c. equal to 0
d. more than 1

Explanation:

Step1: Recall Mechanical Advantage Formula

Mechanical Advantage (MA) is calculated as the ratio of the load force ($F_{load}$) to the effort force ($F_{effort}$), so $MA = \frac{F_{load}}{F_{effort}}$.

Step2: Identify Load and Effort Forces

The load force here is the weight of the crate, which is 100 newtons. The effort force Victoria exerts is also 100 newtons.

Step3: Calculate Mechanical Advantage

Substitute the values into the formula: $MA = \frac{100\ N}{100\ N} = 1$.

Answer:

B. equal to 1
