Here is another way to visualize the forces --  turn the whole system
upside-down:

A #350 weight on the floor with a pulley attached to it.  A cable anchored
to the ceiling, running down through the pulley and then up into your
hand.
How hard do you have to pull on the cable, straight up, to lift the #350
weight?

It's a simple block-and-tackle.
