Problem 27E

Refer to Exercise 15. Assume that F = 750 ± 1 N, R = 0.65 ± 0.09 mm, L0 = 23.7 ± 0.2 mm, and L1= 27.7 ± 0.2 mm. Estimate Y, and find the relative uncertainty in the estimate.

Step-by-Step Solution:

Step 1 of 4</p>

Here we have to find the uncertainty of  young’s modulus for the material

Given tensile force

From this F=750,

From this R=0.65,

Given initial length of the wire

From this =23.7,

Given final length of the wire

From this =27.7,

Step 2 of 4</p>

Here we need to find the uncertainty young’s modulus for the material

Substitute the corresponding values in the above formula

=3347.9
