4. In the figure shown, rod AB (M-2 kg, L-2 m, center of mass C located 1 m above ground) is kept on a rough surface (H-0.5). A horizontal force F = 10 N is applied to the rod at point D, and distance CD-L/3 m. This horizontal force F causes the rod to rotate about B.

ab x x AA Paragraph Styles Dictate PRINCIPLE OF BIOMECHANICS QUESTION 3 (1) The tibia is the shin bone in humans. If the maximum strain it can experience before fracturing corresponds to a 1.1% change in length, what is the maximum force that can be applied to a tibia of cross-sectional area 2.9 cm before fracturing? Assume the Young's modulus for the tibia is E = 1.3 x 100 N/m2. Note: kN = kilonewtons. Select one: a. 94.5 kN b....
