QUESTION 4 a) The human femur bone breaks if compressive stress greater than 1.50 * 10 N/m2 is imposed on it. Assuming the Young's modulus for bone is 1.50 * 1010 N/m2, determine 1) the maximum force that can be exerted on the femur bone in the leg if it has a cross-sectional area of 4.90 x 10-4 m2 by how much does a 0.400 m long bone shorten if this maximum force is applied compressively to the bone. (6...

Assume that Young's Modulus for bone is 1.50 ✕ 1010 N/m2 and that the bone will fracture if more than 1.50 ✕ 108 N/m2 is exerted. (a) What is the maximum force that can be exerted on the femur bone in the leg if it has a minimum effective diameter of 2.70 cm? (b) If a force of this magnitude is applied compressively, by how much does the 28.0 cm long bone shorten?

Bone has a young's modulus of about 18 times 10^9 pa. Under compression, it can withstand a stress of about 163 times 10^6 pa before breaking. Assume that a femur (thigh bone) is 0048 m long, and calculate the amount of compression this bone can withstand before breaking.

By what amount does the 52-cm-long femur of an 73 kg runner compress at this moment? The cross-section area of the bone of the femur can be taken as 5.2×10?4m2 and its Young's modulus is 1.6×1010N/m2.

While unrealistic, we will examine the forces on a leg when one falls from a height by approximating the leg as a uniform cylinder of bone with a diameter of 2.3 cm and ignoring any shear forces. Human bone can be compressed with approximately 1.7 × 108 N/m2 before breaking. A man with a mass of 70 kg falls from a height of 7 m. Assume his acceleration once he hits the ground is constant. For these calculations, g =...

Depending on how you fall, you can break a bone easily. The severity of the break depends on how much energy the bone absorbs in the accident, and to evaluate this let us treat the bone as an ideal spring. The maximum applied force of compression that one man's thighbone can endure without breaking is 7.50 104 N. The minimum effective cross-sectional area of the bone is 3.90 10-4 m2, its length is 0.59 m, and Young's modulus is Y...

Depending on how you fall, you can break a bone easily. The severity of the break depends on how much energy the bone absorbs in the accident, and to evaluate this let us treat the bone as an ideal spring. The maximum applied force of compression that one man’s thighbone can endure without breaking is 6.9 x104 N. The minimum effective cross-sectional area of the bone is 5 x10-4 m2, its length is 0.57 m, and Young’s modulus is Y=9.4x109...

The shaft of the tibia is subjected to compressive forces. The length of the tibia shaft is 0.30 m and the cross-sectional area of cortical bone in the shaft is 0.0002 m2. If the ultimate strength of cortical bone is 200 x 10^6 N/m2 and if the elastic modulus of the shaft of the tibia is 2 x 10^10 N/m2, what is the maximum compressive force (in N) that can be applied to the tibia shaft before compressive failure? Now...

The normal force of the ground on the foot can reach three times a runner's body weight when the foot strikes the pavement. Part A By what amount does the 52-cm-long femur of an 85 kg runner compress at this moment? The cross-section area of the bone of the femur can be taken as 5.2×10−4m2 and its Young's modulus is 1.6×1010N/m2. Express your answer to two significant figures and include the appropriate units.
