stubhead said:I would guess that Young's Modulus would apply the coefficient of elasticity to the entire length of the string when you bend it, if it's sliding in a non-locked nut. Wouldn't 29" of wire have a different, lesser degree of vertical deformation than 25" of wire, for a given amount of sideways force?

ofcourse it would, but this has nothing to do with youngs modulus its about reducing friction between the string and the nut.
