The question
You are a Neuroengincer interested in Biomechanics, for the
purpose of developing better leg prosthetics and broken bone repair
strategies and systems.
An orthopedic bone plate is a flat segment of stainless steel used to
fasten two sections of bone together with stainless steel screws.
Knowing that F= 300N, L = 10 cm, D- 15mm, t= 3mm, the elastic
modulus is 200 GPa, the ultimate strength of the material is 400
MPa.
Calculate:
a) The applied stress. (use figure a)
b) The deformed length. (use figure a)
c) Can we make a hole with a diameter of Smm (as shown in
figure b), explain your answer.
29
Assume that Young's modulus is 1.50 x 1010 N/m2 for bone and that the bone will fracture if
stress greater than 1.50 x 108 N/m2 is imposed on it. If this much force is applied
comprehensively, by how much (in mm), does the 25.0-cm-long bone shorten
Q17. A force compresses a bone by 0.20 mm. The same force compresses a second bone of twice
the length but the same cross-sectional area. The second bone compresses by
A. 0.40 mm
B. 0.10 mm
C. 0.20 mm
D. 0.05 mm
E. 0.80 mm
F. None of the above

- A football (soccer) player can kick the ball with about 4 kN of force. Suppose an athlete accidentally kicks their competitor's tibia instead of the ball. This injury may be modeled by the diagram below, where the kick is represented by force F. Assume that the load is applied directly in the middle of the tibia. For the sake of simplicity, model the bone as a solid beam with 2 cm x 2 cm square cross-sectional area. Note that the pin and roller in the model do not induce reaction moments. Use E = 16 GPa.
