A strip of elastomer 1 cm×1 cm×10 cm is stretched to 25 cm length at T =25C, a stress of 1.5 MPa being required

(a) Assuming a tetrafunctional crosslinking mode, how many moles of network chains are there per cubic centimeter?

(b) What stress is required to stretch the sample to only 15 cm at T = 25C?

(c) What stress is required to stretch the sample to 25 cm length at 100C?

A mass m = 1 kg is suspended from a spring that is stretched 1 cm under the influence of the weight of this mass. Now a periodic force is applied external of F (t) = 200 cos (vt) on the mass, which was initially in static balance. Disregarding all friction, get a relationship for position of the mass as a function of time, x (t). Also determine the value of ω which will cause resonance to occur
