A Force stretches a wire by 1.0mm A second wire of the same material has the same cross section and twice the length. How far will it be stretched by the same force?
b) A third wire of the same material has teh same length and twice the diameter as teh first. How far will it be stretched by the same force?
F = y(delta)L/L0*A Youngs modulus
The Attempt at a Solution
1.0mm = 0.01m
I beleive you have to compare the original youngs mudulus with one that is slightly different... I need some guidelines on how to solve this mathematically please. Also, on a side note, is there a differnence between Youngs modulus/shears modulus/bulk modulus? or all they all aprt of the same idea with different concepts, ie(one uses volume)
