neonofarm [45]

Answer:

334.48

Explanation:

delta T = 4 degrees

m = 20 grams of water

c = 4.181 J / gram

E = 20 * 4.181 * 4

E = 334.48 Joules

Remember to change c to Joules / gram

4181 j / kg * 1 kg / 1000 grams = 4.181 j / gram

goldstein sa. the mechanical properties of trabecular bone: dependence on anatomic location and function. journal of biomechanic
Mice21 [21]

A complicated substance with significant heterogeneity is trabecular bone. Depending on the anatomical region and with age, its elastic and strength qualities change significantly  also sickness.

The relevance of architecture and tissue material qualities is still unclear, despite the fact that these characteristics are highly dependent on density. Interesting facts about the strains the point at which the bone fails is essentially independent of density. Currently being done, there are more sophisticated structure-function relationships that underlie such behavior mechanical characteristics such time-dependent failure, damage, and multiaxial loading accumulation.

The microstructural class of finite element models, especially the "high-resolution" models, offers a special method for investigating such phenomena. With continuing research in this area, it is anticipated that significant understanding will be gained into issues including osteoporosis, bone fracture, bone remodeling, and the design/analysis of bone-implant systems. This article examines the current status of trabecular bone biomechanics, concentrating on the mechanical elements, and makes an effort to pinpoint crucial areas for present and future study.
