look at the simple machine shown below and determine the mechanical advantage. a. 6.8 b. 0.2 c. 9.7 d. 4.4
Answer
Explanation:
Step1: Recall mechanical - advantage formula for inclined plane
The mechanical advantage (MA) of an inclined plane is given by the formula $MA=\frac{l}{h}$, where $l$ is the length of the inclined - plane and $h$ is the height (or in this case, the horizontal distance related to the effort - distance concept for a simple machine). Here, $l = 2.2m$ and $h=0.5m$.
Step2: Calculate mechanical advantage
$MA=\frac{2.2}{0.5}=4.4$
Answer:
D. 4.4
