The figure below shows a horizontal beam clamped at one end with a block attached to the other end.
The block is made to oscillate vertically. The Young modulus 
of the material of the beam is given by
where
is the mass of the block,
is the period of the oscillations and
is a constant.
A student determines the values and percentage uncertainties of , , and . The table below lists the percentage uncertainties.
The student uses the values of , and to calculate the value of as 
.
