Mechanical analog of a hello product is a spring (of spring constant G) and a dash pot (of viscosity u) in parallel which is in series with another spring ( of spring constant G). In other words the system consists of two parts, (I) part1 is a spring and dashpot in parallel and (I) is a spring. The parameters for the product are G =100 and u=200pas and G2=50Pa.the sample is subjected to a constant stress of 5pa a. Derive the expression for strain as a function of time b. What will be the strain of the sample at t=3s after the imposition of stress c. Will the sample reach an equilibrium strain. Explain
