A uniform ladder AB of length 6m and mass 40kg rests in a vertical plane with his end B on smooth horizontal ground and the end A against a smooth vertical wall. A mass 20kg is hung from a point on the ladder at a distance 2m from B. The ladder is kept in equilibrium by rope perpendicular to the wall, attach at one edge to the point B and the other end with point C at the foot of the wall. If size BC equal to 3cm, calculate correct to 1 decimal place 1) the reaction of the ground 2) the tension of the rope
