Answer:
Mechanical advantage = 2.875
Explanation:
Given:
A diagram is shown below for the above scenario.
Length of ramp (Effort arm) = 4.6 m
Height of truck bed ( Resistance length) = 1.6 m
Mechanical advantage (MA) is the ratio of effort arm and resistance length.
So, mechanical advantage is given as,
![MA=\frac{\textrm{Effort arm}}{\textrm{Resistance length}}= \frac{4.6}{1.6}=2.875](https://tex.z-dn.net/?f=MA%3D%5Cfrac%7B%5Ctextrm%7BEffort%20arm%7D%7D%7B%5Ctextrm%7BResistance%20length%7D%7D%3D%20%5Cfrac%7B4.6%7D%7B1.6%7D%3D2.875)
