# Math Help - Force on cart

1. ## Force on cart

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 $\beta$ angle.

Since $\beta > \theta$ the body of the person is dragged down a little bit which explains why the force acting on the ramp is greater than the weight of the person.

I dont get it.

I interpret $\beta$ as the wire pointing 3 degrees above horizontal where his hands pull.

I did: Free-body diagram of cart

$R - mg cos(\theta) = 0$

$T - mg sin(\theta) = 0$

It doesnt work.

Thx
