1) A sample of cross-linked natural rubber (polyisoprene) is found to have a shear modulus of 500 kPa at 25˚C. Determine the force needed to stretch a 100 mm long rod to 150 mm. Note that the original circular cross-section of the rod was 1.0 mm in diameter. What is the diameter of this rod of natural rubber while stretched to 150 mm?

Expert Solution

Consider the Given Data,Here we need to take Poissons ratio as Given,

Now to find the Force needed to stretch the rod Consider,

Now to find the diameter of rod while stretched, Consider,

Therefore the diameter while streched will be reduced to 0.67mm.

Hope you have followed up. Wish A great career ahead. Convey your feedback...

The polymer of choice had this viscosity at 145 °C when its DPw was 700. This polymer has a Tg of 75 °C. Because of polymerization kinetics miscalculation by someone who did not take polymer science, today’s polymer has DPw of 500....
