I got it

no

I think I got the angle which OG makes to left inclined plane, it is 90°-α

Intersecting point of diagonals and 3 forces.

(1) From AG=OG since they are diagonals, so AOG = GOA = 45° because AGO = 90° which is caused by intersecting of two diagonals. So OG makes 45° angle to the left inclined plane. (2) Circular path?

The other diagonal passes through the mass centre of plate. I have drawn the left end plate going down and the other going up. The mass centre of the new diagram is located at same position of the first diagram. Right?

I have drawn my diagram, it looks like rectangle which has L as diagonal. I think OG is L/2.

there is

The angle which the plate makes to horizontal, θ, is 90°-β. How could this help to solve problems?

The sum of vectors is zero The Vectors cross or intersect at same point and they are in the same plane.

Ah, I see. So the NA makes α angle with vertical direction or 90° to the left inclined plane. (2) I understand that you meant slope of both planes, if I understand correctly I think there is a angle which make this system possible. Because there are normal forces to make it become steady.

(1) Isn't NA perpendicular to the plate? It looks same as a typical rectangular object on a inclined plane problems (2) I think I found the angle which plate makes to the horizontal now, it is 90-β. But I don't know how to find the answer to your latest questions.

(1) I think the angle that NA makes to plate is 90 because it's normal force. (2) I see. (3) I really can't find the angle which the plate make to the horizontal. Could you give me a hint please?

(1) I think it is α (2) Isn't it L/2? (3) α ?

Homework Statement A thin stiff uniform rectangular plate with width L (L =AB) is lying on two inclined surface as shown in Fig. 3-1. The angle between the horizontal surface and the left inclined surface is α, and that between the horizontal surface and the right inclined surface is β. It is...
