(The bridge is supported by the cable and hinges only.) The mass of the bridge is 2500 kg. in newtons, in the cable ted T 26108 9 Potential 92% ted cos) Submissions atan acotanOsinhO . Degrees Hint Feedback: deduction per feedback. Part (b) Find the of the force, in newtons, eExplanation / Answer
using equilibrium of force about the left hinge
T Sin40 (7.5 + 1.5) = w 1.5 + (mg) (4.5)
T Sin40 (9) = (2500 x 9.8) (1.5) + (925 x 9.8) (4.5)
T = 13404 N
