Question 2. 120 pts] As the Society for Biomaterials notes: "Sutures are one of the most important medical devices that is used in surgery. In cardiovascular procedures the sutures can be

used to suture tissue with tissue, or tissue with an implantable device. These are the available in various sizes (suture diameter) and polymers (absorbable and non-absorbable). Further, the sutures vary in forms, they can be either braided, monofilament, or knotless sutures." You have been asked to evaluate a new suture thread material for use in cardiovascular surgery. The material is highly biocompatible and could set a new standard for sutures, but there are concerns that it is not strong enough. Surgeons have complained that the suture thread break too easily when being pulled through tissue. You have been hired to model this form of failure and make design recommendations. A. [4pts] Draw a free body diagram that models a section of suture thread being pulled straight through a block of tissue. Assume the needle pulls on one end of the cylindrical thread with force F (N), the block of tissue has length B (such that B
