Two masses 7 kg and 12 kg are connected at the two ends of a metal wire that goes ove a frictionless puulley. What should be in the minimum radius of the wire in order that the wire does not break,if the breaking stess of the metal is 1.3 xx 10^(8) N //m^(2) ?

Two block of mass m and M are connected means of a metal of a metal wire passing over a frictionless fixed pulley. The area of cross section of the wire is 6.67xx10^(-9)m^(2) and its breaking stress is 2xx10^(9)Nm^(-2) . If m = 1kg. Find the maximum value of M in kg for which the wire will not break. (g=10m//s^(2)) .
