A block of Jell-O is resting on a plate. The Jell-O stands 0.03 m tall and in the shape of a square that is 0.07 m in length. You are bored, waiting for dinner and push tangentially across the top surface with a force of 0.45 N. The top surface moves a distance of ∆x = 6.0 x 10^-3 m relative to the bottom surface. What is the shear modulus of Jell-O?

The legs of a weight lifter must ultimately support the weights he has lifted. A human tibia (shinbone) has a circular cross section of approximately 3.6 cm outer diameter and 2.5 cm inner diameter. (The hollow portion contains marrow. ) if a 90 kg lifter stands on both legs, what is the heaviest weight he can lift without breaking his legs, assuming that the breaking stress of the bone is 200 MPa?

Humans can bite with a force of approximately 792 N. If a human tooth has the Young's modulus of bone, a cross-sectional area of 1.3 cm2, and is 1.7 cm long, determine the change in the tooth's length during an 7.92 ✕ 102 N bite.

A 1.2 x 10-³-kg house spider is hanging vertically by a thread that has a Young's modulus of 4.4 x 10⁹ N/m² and a radius of 18 x 10 m. Suppose that a 65-kg person is hanging vertically on an aluminum (Young's modulus 6.9 x 1010 N/m²) wire. What is the radius of the wire that would exhibit the same strain as the spider's thread, when the thread is stressed by the full weight of the spider? Number i Units

Humans can bite with a force of approximately 795 N. If a human tooth has the Young's modulus of bone, a cross-sectional area of 1.3 cm2, and is 1.8 cm long, determine the change in the tooth's length during an 7.95 ✕ 102 N bite.

A sphere of copper has a radius of 8.00 cm and is compressed uniformly by a force of 5.00 × 108 N. The bulk modulus for copper is 140 x 10⁹ N/m². Calculate the sphere's change in volume AV after compression. Calculate the sphere's final radius R. AV = R = 3.81 x107 Incorrect 0.075 -7 Incorrect m³ m

A nylon rope used by mountaineers elongates 1.10 m under the weight of a 65.0-kg climber. If the rope is 45.0 m in length and 7.0 mm in diameter, what is Young’s modulus for nylon?

Assume a human leg contains a 50cm long bone with an average cross section of 3cm. 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 1010 Pa Answer:

A man with a mass of 68.3 kg stands on one foot. His femur has a cross-sectional area of 8.00 cm2 and an uncompressed length 50.4 cm. Young’s modulus for compression of the human femur is 9.40 × 109 N/m2. What is the fractional length change of the femur when the person moves from standing on two feet to standing on one foot?
