Question

The Young's Modulus Y is determined by stretching
a wire by using formula
Y = 4FL
Id²l
>
F is the stretching force L is length of wire,
l is increase in length and dis diameter of
Cross-section of wire. IF F is of order of 500 N
and known to 1
part in 1000, L is of order
of 3 m and measured with accur.
l is of order 5mm measured to onl mm and
d I mm
correct up to 0.01 mm. Estimate
the percentage error in Y.
