Assignment Help Mechanical Engineering
Reference no: EM13887349

An elastomer was suddenly stretched in tension and the elongation was held constant. After 10 min, the tensile stress in the polymer dropped by 12%. After an extremely long time the stress dropped to 48% of its original value.

A. Find the relaxation time, τ , for stress relaxation.

B. How long will it take the stress to drop to 75% of its initial value?
