Common sports injuries result in the tearing of tendons and ligaments due to overstretching. If the anterior cruciate ligament (ACL) in an athlete's knee has a length of 1.30 cm, a breaking point of 187 MPa, and a Young's modulus of 600 MPa, how far must it be stretched from its relaxed length to tear it? mm

A 100-N weight is attached to a free end of a metallic wire that hangs from the ceiling. When a second 100-N weight is added to the wire, it stretches 3.0 mm. The diameter and the length of the wire are 1.0 mm and2.0 m, respectively. What is Young’s modulus of the metal used to manufacture the wire?
Two rods, one made of copper and the other of steel, have the same dimensions. If the copper rod stretches by 0.15mm under some stress, how much does the steel rod stretch under the same stress?
Assume Youngs modulus for bone is 1.50 1010 N/m2. The bone breaks if stress greater than 1.50 108 N/m2 is imposed on it. (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 2.50 cm? (b) If this much force is applied compressively, by how much does the 25.0-cm-long bone shorten?
What Is Static Equilibrium? Problems 13 are grouped. 1. C A ball is attached to a strong, lightweight rod (Fig. P14.1). The rod is supported by a horizontal pin near the top. The ball is at rest. Is the ball in static equilibrium? If not, why not? If so, which type of equilibrium is itstable, unstable, or neutral? Hint: What would happen if you displaced the ball slightly? FIGURE P14.1
Can Young’s modulus have a negative value? What about the bulk modulus?
A 90-kg mountain climber bangs from a nylon rope and stretches it by 25.0 cm. If the rope was originally 30.0 m bog and its diameter is 1.0 cm, is Young’s modulus for the nylon?
Compression of Human Bone. The bulk modulus for bone is 15 GPa. (a) If a diver-in-training is put into a pressurized suit, by how much would the pressure have to be raised (in atmospheres) above atmospheric pressure to compress her bones by 0.10% of their original volume? (b) Given that the pressure in the ocean increases by 1.0 * 104 Pa for every meter of depth below the surface, how deep would this diver have to go for her bones to compress by 0.10%? Does it seem that bone compression is a problem she needs to be concerned with when diving?
The compressivestrength of our bones is important in everyday life. Young’s modulus forbone is about 1.4 * 10^10 Pa. Bone can take only about a 1.0% changein its length before fracturing. (a) What is the maximum force that canbe applied to a bone whose minimum cross-sectional area is 3.0 cm2?(This is approximately the cross-sectional area of a tibia, or shin bone,at its narrowest point.) (b) Estimate the maximum height from which a70 kg man could jump and not fracture his tibia. Take the time betweenwhen he first touches the floor and when he has stopped to be 0.030 s,and assume that the stress on his two legs is distributed equally.
A 2m long, 1mm diameter wire is suspended from the ceiling. Hanging a 4.5kg mass from the wire streches the wire's length by 1mm. What is the Young's modulus for this wire? I just need teh answer please.
A particular human hair has a Young's modulus of 3.63×109 N/m2 and a diameter of 145 μm. If a 228 g object is suspended by the single strand of hair that is originally 20.0 cm long, by how much Δ? hairΔL hair will the hair stretch? If the same object were hung from an aluminum wire of the same dimensions as the hair, by how much Δ?AlΔLAl would the aluminum stretch? If the strand of hair is modeled as a spring, what is its spring constant ?hair?khair?
Assume a human leg contains a 50cm long bone with an average cross section of 3cm2. By how much (in micrometres) does the bone shorten when the entire body weight of the person is supported by that one leg. The body weight is 700N and the Young's modulus for bone is 1.8 x 100 Pa
To stretch a relaxed biceps muscle 2.5 cm requires a force of 25 N. Find the Young's modulus for the muscle tissue, assuming it to be a uniform cylinder of length 0.24 m and cross-sectional area 47 cm².
