Refer to Exercise 12 in Section 3.2. Assume that 
= 50 ± 1 MPa,w = 1.2 ± 0.1 mm, and k = 0.29 ±0.05 
.
a. Estimate ?, and find the uncertainty in the estimate.
b. Which would provide the greatest reduction in the uncertainty in 
: reducing the uncertainty in ?0 to 0.1 MPa, reducing the uncertainty in w to 0.01 mm, or reducing the uncertainty in k to 0.025 
?
c. A new, somewhat more expensive process would allow both 
and w to be measured with negligible uncertainty. Is it worthwhile to implement the process? Explain.
