Hi
Description in the attached picture.
How can the ramp exert a force larger than the weight of the person !! (?)
Also, I am not sure how to interpret the $\displaystyle \beta $ angle.
Hi
I dont get it.
I interpret $\displaystyle \beta $ as the wire pointing 3 degrees above horizontal where his hands pull.
I did: Free-body diagram of cart
$\displaystyle R - mg cos(\theta) = 0 $
$\displaystyle T - mg sin(\theta) = 0 $
It doesnt work.
Thx
