Identifying Forces and Directions in Torque and Equilibrium

[Intr3pid]

hello everyone

I recently started learning about torque and I'm having a lot of trouble with the first 2 questions. Can someone help me out with the first two questions?

btw, I don't quite understand how to draw the free body diagram for the first question.

PS the questions are located on the attachments

Try considering just one 'leg' of the tripod

can someone help me out please?

I'm really stuck.

For the first one:
Each leg of the tripod needs to support one third of the object's weight. Keep in mind that this force is being applied strictly vertical

I still don't quite get it.

Lets start at the bottom of one leg. What forces do you indentify and in what direction are they?
