- Assume Young’s modulus for bone is 1.40×1010 N/m2 . The bone breaks if stress greater than 1.50 × 109 N/m2 is imposed on it. (i) What is the maximum force that can be exerted on the femur bone in the leg if it has a minimum effective diameter of 2.50 cm? (ii) If this much force is applied compressively, by how much does the 20.0 cm long bone shorten?Orb Spiders make silk with a typical diameter of 0.15mm. 1)A typical orb spider has a mass of 0.50 g.
