Moved from a technical forum, so homework template missing

Forgive my current brain fart, but just posting here for some confirmation of my thoughts.

I have a cart with a similar setup to a rear wheel wheelbarrow. Assuming static conditions, I am trying to determine the vertical reaction force (FA) from the ground when applying a horizontal force to the handle (F1). There is a moment Mc about the wheel (pivot point / fulcrum) and the dimensions are provided.

Per my assumptions is an getting the following results:

Value Units

Force F1 = 50 pounds

Distance Y = 7.872 inch

Distance X = 13.065 inch

Moment due to F1: M = F*d1 = 50*( 36.6-3.01) = 1679.5 inch-pound

Force: FA = M/d2 = 1679.5/(15.32) = 109.6279 pound

Is the input force F1 the same as F2 despite being applied after different locations.

Am I over simplifying this or have I correctly remember what my professors taught me years ago?

Thanks in advance for anyone thoughts and comments.,
