A cylinder having mass 40 kg is hung by means of cables AB and AC which arc attached to the top of the vertical wall. The distance of points B and C on the wall from a line along the wall parallel to the axis of cylinder are 8 m and lO m respectively. A horizontal force along the line perpendicular to the wall has been applied at the cylinder which pulls it by a distance 1·2 m away from the wall. The point A is on the cylinder and it is I0 m below BC. Determine tension in each cable and the force applied at the cylinder.
