A telephone cable is clamped at A to the pole AB. Knowing that the tension in the right-hand portion of the cable is T2 = 1000 lb, determine by trigonometry (a) the required tension T1 in the left-hand portion if the resultant R of the forces exerted by the cable at A is to be vertical, (b) the corresponding magnitude of R.

Respuesta :

Answer:

(a) T1 = 938.3lb

(b) R = 665.5lb

The detail solution to this problem can be found in the attachment below.

This problem was solved by resolving the forces along the vertical and horizontal and equating to Rx and Ry respectively. Rx = 0 because the resultant is directed along the vertical.

Explanation:

See attachment below for the full solution.
