Physics · Mechanics of Solids
Three metal balls are suspended vertically in a series hanging from each other by three wires (a, b, and c) of equal length. Wire 'a' is at the top supporting all balls, wire 'b' is in the middle, and wire 'c' is at the bottom supporting the lowest ball. The masses of the balls, starting from top to bottom, are 2 kg, 4 kg, and 3 kg respectively. The wire diameters in the same top-to-bottom order are 2 mm, 1.2 mm, and 1 mm respectively. What is the correct order of increasing tensile stress in the wires?
