Practice ASVAB mechanical advantage.?
If a ramp measures 6 feet in length and 3 feet in height, an object weighing 200 pounds will require how much effort to move using the ramp?
200
100
50
or
300.
I know that mechanical advantage is simply the ratio of force over distance. Using no ramp and lifting directly into the air there is a pressure of 200 lbs for 3 ft. If you use a 6 foot ramp shouldn't the force be 100lbs over 6 ft? Twice the distance, half the effort right?
Practice Asvab says 50Lbs is the correct answer. I will just assume they messed up. I noticed a few biology questions that were poorly written and some physics were just wrong. Thank you for assuring my sanity.
