The accepted value (http://www.engineeringtoolbox.com/young-modulus-d_417.html) of Youngs Modulus of elasticity is 1.3× 108 kg m-1 s-2, which makes the answer found from the experiment I fire performed very simil! ar, almost identical to the accepted value. However the error of the found value is very big, and...If you want to get a full essay, order it on our website: BestEssayCheap.com
