A rigid bar of mass M is supported symmetrically by three wires each of length l. Those at each end are ofcopper and the middle one is of iron. The ratio of their diameter, if each is to have the same tension, is equal to
(a)YcopperYiron(b) √YironY copper(c)Yiron2Ycopper2(d)YironYcopper
Problem 12-76
could you give the full solution, so that I can understand the calculation
A homogeneous bar, of mass m = 100kg, is suspended from three symmetrically located vertical wires of the same length. Determine the tension of the wires, if the middle wire is steel and the other two are copper. The cross-sectional area of all the wires is equal. The Young's modulus of steel is twice that of copper.
