Answer / Solution

UNSOLVED

Estimate the precision to which the Young’s modulus, of the wire can be determined by the formula , given that the applied tension ​ F = 500​ N ​ , the length of the loaded wire, ​l = 3​ m ​ , the diameter of the wire, ​ d = 1​ mm ​ , the extension of the wire, ​ e = 5​ mm and the error associated with these quantities are 0.5N, 2mm, 0.01mm and 0.1mm respectively.
