The radii of two wires of a same material are in ratio 2:1. if the wires are stretched by equal forces, the stress produced in them will be what?

Question

Saurabh Koranglekar · Answer

Arun · Answer

STRESS (S)=FORCE(F)/AREA (A)
S IS INVERSLY PROPORTIONAL TO AREA
S=1/πR2 π, BEING A CONSTANT THEREFORE WE CAN SAY S IS INVERSLY PROPORTIONAL TO R2
S1=1/R2
S2=1/R22
DIVIDING 1 AND 2 WE GET

S1/S2=R2^2/R1^2

THEREFORE THE RATION IS 1:4
