You are given a system model that is composed of a single spring and single dashpot that is being used to represent a viscoelastic material. The force in the dashpot is 3 N and the force in the spring is 3 N and the force for the overall system is 3 N. The displacement in the dashpot is 3 mm and the displacement in the spring is 5 mm. The overall displacement for the system is [displacement] mm and the spring and dashpot are in [orientation].

You are trying to learn more about the Achilles tendon and found an interesting article that investigates the material properties of this tendon when it is unloaded compared to a control condition. Biological materials continue to remodel with loading, but it is also important to understand how the tissue behaves in the absence of loading. This article uses Botox to paralyze the muscle and force unloading in the subjects (rats). Below you see a key figure from the article demonstrating experimental observations across different groups during: a.) cyclic loading b.) creep at 40 Nc.) stress relaxation You do not need to reference the article to answer the questions below but the complete citation is provided for you if you wish.Khayyeri H, Blomgran P, Hammerman M, Turunen MJ, Löwgren A, Guizar-Sicairos M, Aspenberg P, Isaksson H. Achilles tendon compositional and structural properties are altered after unloading by botox. Scientific Reports. 2017 Oct 12;7(1):1-0.
