A material can be characterized with a standard linear model (see figure

A material can be characterized with a standard linear model (see figure below). The material is loaded with a step in the force at time t 0. At time t t the material is suddenly unloaded stepwise. (a) Derive the strain response for this loading history. (b) Make a drawing of the strain response as a function of time. (c) Calculate de /dt for t= 0. %3D
