The light boom AB is attached to a vertical wall by a ball and socket joint at A and supported by two cables at B. A force Pis applied at B where P = 14i - 15j kN.Note that the reaction force at A acts along the boom because it is a two-force member. Calculate the magnitude of the reaction force at A in kN.

Please show clear work and free body diagram if possible

Consider the following truss, supported by a smooth pin at point A and by a roller at point E on which various external forces are acting. For each node B, C, D draw the corresponding free-body diagram and find all the forces in the members of the truss, establishing whether these forces are compression (C) or tension (T). Calculate the external forces on supports A and E
