Question:

For the hook support of Problem 2.11, determine, using trigonometry,

(a) The magnitude and direction of the smallest force P for which the resultant R of the two forces applied to the support is horizontal,

(b) The corresponding magnitude of R. Problem 2.11: Two forces are applied as shown to a hook support. Using trigonometry and knowing that the magnitude of P is 14 lb, determine (a) the required angle α if the resultant R of the two forces applied to the support is to be horizontal, (b) the corresponding magnitude of R.
