Initially a cable is 20 meters long. The cable is stretched to a length of 20.1 m. The length of the cable is held constant. The material can be modeled using a Maxwell model with an elastic modulus of 2 GPa and a viscosity coefficient of 500 TPa. sec. (30 points) a) Sketch the problem
b) Sketch the Maxwell model
c) Estimate the stress in the cable immediately after stretching
d) Estimate the stress in the cable 24 hours after stretching
e) Estimate the stress in the cable 7 days after stretching
f) Sketch the stress-time curve in the cable
