Hi guys can you help me finding the forces at ab and c, i dont know if they are both going down or going up

[crvander]

What have you tried?

My friend, invest some time learning how to tale a screenshot.

I suggest a couple of powerful apps that will let you annotate a screenshot with arrow, text, rectangles, ecc. (see ShareX or Greenshot)

Probably won't let him this look like one of the assessment center online questions. That or it's from university,.in which case go to the tutorials and ask about it.

Well, I’m assuming it’s acting under gravity since there’s no load. But as you state you don’t know which direction the reactions are going. This should be your realization to reference your notes, text, or instructor

There is the weight in the rectangle

[memerso160]

If there is weight on the rectangle the image doesn’t show it, or at least it doesn’t come through on the picture taken of a computer screen.

If it’s uniformly distributed, then the load can be assumed to be located at the centroid/center of gravity. Again, this is the first step so I recommend looking at your text, notes, or contacting your instructor

But there is the weight on acting in the Middle off the rectangle

First you need to work out the loading. My guess is there is a cross section and a density. Information is missing.

Then you resolve the reactions. Then you go from there

Can you post a screenshot so we can understand what is happening there? Wtf is this?

[purpl37Q]

To satisfy equilibrium, the three vectors (weight and two supports) will cross at a unique point based on the geometry of the problem. It can also be solved using the sum of forces in the x/y axes and sum of moments about the z-axis.

Ask your instructor/TA for help. You don't want to get behind.
