A cable is replaced by another one of the same length and material but twice the diameter.How does this affect the maximum load it can support without exceeding the elastic limit

Two wires A and B have equal lengths and are made of the same material. But the diameter of A is twice that of wire B. Then for a given load

Two wires of the same length are made of different materials. Diameter of the one is 2 mm and that of the other is 4 mm. When these two wires are stretched by the same force, the first one's elongation is twice the second's.compare their Young's modulus.

A steel cable with a radius of 1.5 cm supports a chair-lift at a ski area. IF the maximum stress does not exceed 10^8 N.m^-2 , what is the maximum load that the cable can support?
