  1. A 70 kg person is participating in a weightlifting competition. During a lift, the person’s femur bone experiences a force of 1000 N. Calculate the stress on the femur bone. (Assume the cross-sectional area of the femur bone is 5 cm²)

  2. A 17-year-old teenager is diagnosed with scoliosis, a condition where the spine curves sideways. The curvature of the spine is measured to be 20 degrees. If the length of the spine is 60 cm, calculate the lateral displacement caused by scoliosis.

  3. A 16-year-old athlete is training for a marathon. During a long-distance run, the athlete’s body temperature rises to 39°C. If the normal body temperature is 37°C, calculate the percentage increase in body temperature.

  4. A 17-year-old student is involved in a car accident and fractures their radius bone. The doctor recommends a cast to immobilize the bone for 6 weeks. If the student’s radius bone is 25 cm long, calculate the percentage of time the bone will be immobilized due to the cast.

  5. A 16-year-old girl is diagnosed with osteoporosis, a condition characterized by low bone density. The girl’s bone density is measured to be 2 standard deviations below the average bone density for her age group. If the average bone density for her age group is 1.2 g/cm³, calculate the girl’s bone density.

  6. A 17-year-old boy is participating in a high jump competition. During a jump, the boy’s tibia bone experiences a force of 1500 N. If the cross-sectional area of the tibia bone is 4 cm², calculate the strain on the bone.

  7. A 16-year-old student is studying the effects of exercise on bone density. The student measures the bone density of 20 participants before and after a 6-month exercise program. If the average bone density before the program was 1.5 g/cm³ and after the program was 1.7 g/cm³, calculate the percentage increase in bone density.

  8. A 17-year-old athlete is training for a weightlifting competition. During a lift, the athlete’s humerus bone experiences a force of 1200 N. If the cross-sectional area of the humerus bone is 6 cm², calculate the pressure on the bone.

  9. A 16-year-old girl is diagnosed with osteoarthritis, a degenerative joint disease. The girl’s knee joint has lost 50% of its cartilage thickness. If the original cartilage thickness was 5 mm, calculate the current cartilage thickness.

  10. A 17-year-old student is studying the effects of nutrition on bone health. The student measures the bone mineral density (BMD) of 30 participants who consume different amounts of calcium daily. If the average BMD for participants consuming less than 1000 mg of calcium daily is 0.8 g/cm² and for participants consuming more than 1000 mg of calcium daily is 1.2 g/cm², calculate the percentage difference in BMD between the two groups.

  1. A person weighing 70 kg is lifting weights and their thigh bone (femur) experiences a force of 1000 N. If the cross-sectional area of the femur bone is 5 cm², how much stress is acting on the bone?

  2. A 17-year-old has been diagnosed with scoliosis, a condition where the spine curves sideways. The curvature of their spine measures 20 degrees. If the length of their spine is 60 cm, how much does their spine shift sideways due to scoliosis?

  3. During a long-distance run, a 16-year-old athlete’s body temperature rises to 39°C. If the normal body temperature is 37°C, what is the percentage increase in their body temperature?

  4. A 17-year-old student fractures their forearm bone (radius) and needs to wear a cast for 6 weeks. If the length of their radius bone is 25 cm, what percentage of time will the bone be immobilized due to the cast?

  5. A 16-year-old girl has been diagnosed with osteoporosis, a condition characterized by low bone density. Her bone density is 2 standard deviations below the average for her age group. If the average bone density for her age group is 1.2 g/cm³, what is her bone density?

  6. During a high jump, a 17-year-old boy’s shin bone (tibia) experiences a force of 1500 N. If the cross-sectional area of the tibia bone is 4 cm², how much strain does the bone undergo?

  7. A 16-year-old student measures the bone density of 20 participants before and after a 6-month exercise program. If the average bone density before the program was 1.5 g/cm³ and after the program was 1.7 g/cm³, what is the percentage increase in bone density?

  8. While weightlifting, a 17-year-old athlete’s upper arm bone (humerus) experiences a force of 1200 N. If the cross-sectional area of the humerus bone is 6 cm², what is the pressure on the bone?

  9. A 16-year-old girl has been diagnosed with osteoarthritis, a degenerative joint disease. Her knee joint has lost 50% of its cartilage thickness. If the original cartilage thickness was 5 mm, what is the current cartilage thickness?

  10. A 17-year-old student measures the bone mineral density (BMD) of 30 participants who consume different amounts of calcium daily. If the average BMD for participants consuming less than 1000 mg of calcium daily is 0.8 g/cm² and for participants consuming more than 1000 mg of calcium daily is 1.2 g/cm², what is the percentage difference in BMD between the two groups?
