Example 6
The crane consists of the beam AB, whose lower end is connected by a joint A to the wall, and the upper end is supported by a horizontal rope BC. Determine the tension T in rope BC and the vertical projection \(N_A\) of the support reaction at A, if the weight P is P=2 kN, the weight of the beam Q=1 kN is attached at the midpoint of AB, and the angle \( \alpha=45^o \).
