The breaking force for a wire of diameter D of a material is F . The breaking force for a wire of the same material of radius D is

Options

  1. AF
  2. B2 F
  3. CF 4
  4. D4 F

Correct answer

D. 4 F

Step-by-step solution

Breaking stress = Breaking force Area = constant aligned F ( D^2 4 ) & = F^ D^2 F^ & =4 F aligned
