A suspender rod of a suspension bridge is 25.0 m long. If the rod is made of steel, what must its diameter be so that it does not stretch more than 1.0 cm when a 2.5 × 104 -kg truck passes by it? Assume that the rod supports all of the weight of the truck.
A spring, with a spring constant of 750 N/m, is hung vertically from the ceiling. If a mass of 500 kg is added to this spring, how much will it elongate?
A 25-ft chain with a weight of 30 lb is suspended between two points at the same elevation. Knowing that the sag is 10 ft, determine (a) the distance between the supports, (b) the maximum tension in the chain.
