hey mate here is your answer⤵⤵

Really, Young's modulus of small metal fragment having sizescale mentioned (tens of micrometers) is not changed essentionally in comparisonwith value measured for "large" block of material. Correspondingly, in this case we mayconsider that stiffness of wires depends on their diameter and length only. 

Hope this will help you✌
