# Why is the weight going upward? Statics

## Homework Statement

In the first problem in the link above, why is the weight pointing upwards instead of downwards? I thought there will be a different force prolly called Fae pointing upwards with the weight pointing downwards.

Thanks

In the first part I think they just used W to represent the force acting in the vertical chain connected to A.

But in the calculations, W = mg, where m = 200kg. I still dont get it...

Yeah I see it now. Not too sure why exactly they did that other than to get a positive answer. If you had W acting downwards, then you'd get the two forces to be negative meaning that the forces act in the opposite direction.
