A light rod of length 200 cm is suspended from the ceiüng onzontålly by means of two
vertical wires of equal lengths tied to its ends. One of the wires is made of steel and is of
cross-sectional area O. 1 cm2 and the other is af brass of cross-sectional area 0.2 cma. Find steel
out the position along the rod at which weights may be hung toproduce
(a) equal stress in both wires,
(b) equal strains in both wires.
