As an engineer for an implant design company, the FDA contacts you because it is receiving reports that your company's pin implant is failing in patients, a less than ideal situation. Your pin is used to stabilize a fracture of the fifth metatarsal and the FDA would like to work with you to identify the problem. After analyzing how the adhesive for the pin (aka the beam) attaches into the bone, you draw an approximate free body diagram of the complex loading and connection to other biologic structure (aka the supports) shown below. If the magnitude of the flexural yield stress (this is a synonym for bending yield) is 42MPa and you don't want any plastic deformation, what is the minimum required height, h, of your pin? Justify with an appropriately labeled moment diagram. 3 N/cm IB 2 cm + 2 cm RE CADEAU 1 cm 1 cm 6mm h As an engineer for an implant design company, the FDA contacts you because it is receiving reports that your company's pin implant is failing in patients, a less than ideal situation.

Answer rating: 100% (QA)

Solutions Step 1 To determine the minimum required height h of the pin we need to first calculate the maximum bending moment that the pin will experie... View the full answer
