The cable between the two towers of a suspension bridge hangs in the shape of the curve T y = W cosh (7). where T' is the tension in the cable at its lowest point and w is the weight of the cable per unit length. This curve is called a catenary. T T ―. The 'sag' of the cable is defined as the W W Suppose the cable stretches between the points x = difference between the height of the cable at the highest and lowest points. Show that the sag of the cable T defined above can be expressed as a multiple of W Sag Enter the missing coefficient in the blank that completes the expression below. Round the answer to three decimal places. = i and x = T W
