A suspender on a suspension bridge consists of a cable that passes over the main cable (see figure) and supports the bridge deck, which is far below. The suspender is held in position by a metal tie that is prevented from sliding downward by clamps around the suspender cable.
Let P represent the load in each part of the suspender cable, and let u represent the angle of the suspender cable just above the tie. Finally, let sallow represent the allowable tensile stress in the metal tie.
(a) Obtain a formula for the minimum required cross-sectional area of the tie.
(b) Calculate the minimum area if P = 130 kN, u = 75°, and sallow = 80 MPa.
