Question

what output force is generated when an input force of 630 n is applied to a machine with a mechanical advantage of 3? 21 n 180 n 310 n 1890 n

Explanation:

Step1: Recall mechanical advantage formula

Mechanical Advantage (MA) is defined as $\text{MA} = \frac{\text{Output Force}(F_o)}{\text{Input Force}(F_i)}$, so rearrange to solve for output force: $F_o = \text{MA} \times F_i$

Step2: Substitute given values

Input force $F_i = 630\ \text{N}$, $\text{MA} = 3$.
$F_o = 3 \times 630\ \text{N}$

Step3: Calculate the result

$F_o = 1890\ \text{N}$

Answer:

D. 1890 N
