14.4. The initial stress on a polymeris arcere periment is 10 Nm. This load is increased by 10 Nim and 10 N/m after 10 and 10's, respectively. Assuming that the Boltzmann superposition principle holds for this material, find the strain after 10's. The creep compliance for the material is given by 10* (1-16). ... Q2. If a 1.0 cm cube of such an ideal rubber is stretched to 1.2 cm by a force of 3 N, what str is going to be required to stretch a 5 cm strip of the same rubber to a length of 7.5 cm? a Lotton
