Leaning triangular panel A rough floor lies in the horizontal plane z = 0 and the planes x = 0, y = 0 are occupied by smooth vertical walls. A rigid uniform triangular panel ABC has mass m.
The vertex A of the panel is placed on the floor at the point (2, 2, 0) and the vertices B, C rest in contact with the walls at the points (0, 1, 6), (1, 0, 6) respectively.
Given that the vertex A does not slip, find the reactions exerted by the walls. Deduce the reaction exerted by the floor.
