Q3: A telephone cable is clamped at A to the pole AB. Knowing that the tension in the left-hand portion of the cable is T1 = 800 lb, determine by trigonometry (a) the required tension T2 in the righthand portion if the resultant R of the forces exerted by the cable at A is to be vertical, (b) the corresponding magnitude of R. 25° T₂

The frame ACD is hinged at A and D and is supported by a cable that passes through a ring at B and is attached to hooks at G and H. Knowing that the tension in the cable is 625.00 N, determine the moment about the diagonal AD of the force exerted on the frame by portion BG of the cable. y 0.925 m 0.35 m G 0.5 m B 0.875 m 0.5 m P H D 0.75 m 0.75 m The moment about the diagonal AD of the force exerted on the frame by portion BG of the cable is N.m.
