Two cables of the same gauge are attached to a transmission tower at B . Since the tower is slender, the horizontal component of the resultant of the forces exerted by the cables at B is to be zero. Knowing that the mass per unit length of the cables is 0.4 kg/m, determine (a) the required sag h, (b) the maximum tension in each cable.
A 500-ft-long aerial tramway cable having a weight per unit length of 2.8 lb/ft is suspended between two points at the same elevation. Knowing that the sag is 125 ft, find (a) the horizontal distance between the supports, (b) the maximum tension in the cable.
Show your work. Three cables are connected at A, where the forces P and Q are
applied as shown. Knowing that Q=0, find the value of P , and tension in cables AB and
AD for which the tension in cable AC is 710 N.
