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.
