Answer:
1.48 Mpa
Explanation:
Given that For a polymer that was maintained at constant strain, an initial stress of 2.76 MPa decreases to 1.72 MPa after 6 hr. To estimate the stress remaining after 30 hr, we must first find the decay constant by using the exponential equation.
Therefore, the estimate of the stress remaining after 30 hr, is 1.48Mpa.
