Question 5.1

5.1 The light boom AB is attached to the vertical wall by a ball-
supported by two cables at B. A force P = (12i – 16k ) kN is applied at B. Note that R.
the reaction at A, acts along the boom, because it is a two-force body. Compute the cable
Socket Joint at A and
tensions and RA.
5.2 The cables exert the forces shown on the pole. Assuming the pole is supported by a
ball-and-socket joint at its base; Determine the components of reaction at A. The forces of
140 kN and 75 kN lie in a horizontal plan.
