Two rods A and B , each of equal length but different materials are suspended from a common support. The rods A and B can support a max load of W1 = 600 N and W2 = 6000 N, respectively. If their cross section areas are A1 = 10 mm 2 and A2 = 1000 mm2, respectively, then Identify the stronger material.

										Dear Student Mr. Sanchit;

the stronger material is which one who can sustain higher stress value. this property is not depends on total load.
So first of all , we have to calculate the maximum stress which material can sustain.

stress = load/cross section area
stress1 = 600/10 = 60 N/mm2
stress2 = 6000/1000 = 6N/mm2

so stress 1 is higher than stress 1
So materials 1 can sustain at higher stress. so stronger material is 1.
