The string has one end attached to the rod at \(B\) and the other end attached to a point \(C\) of the wall. The point \(C\) is 0.5 m vertically above \(A\) (see diagram). Find

1. the tension in the string,
2. the horizontal and vertical components of the force exerted on the rod by the wall at \(A\).
