Describe the microscopic features of the osseous tissue that help long bones withstand compressive forces without breaking?
Osseous tissue, or bone, features a dense matrix composed of collagen fibers and mineral salts, primarily hydroxyapatite, which provide strength and flexibility. The arrangement of osteons, or Haversian systems, within compact bone allows for efficient load distribution and resistance to compressive forces. Additionally, the presence of trabecular bone in the interior of long bones creates a lightweight yet strong structure that effectively absorbs and redistributes stress. These microscopic adaptations enable long bones to withstand significant compressive forces without fracturing.

What is an example of compressive strength?
Concrete's capacity to withstand compressive forces is an illustration of compressive strength. A concrete structure, like a column or a beam, experiences pressure when it is subjected to a load. Concrete's capacity to withstand this pressure without breaking or deforming is measured by its compressive strength. For instance, structural concrete must have a compressive strength of at least 25 megapascals (MPa), which indicates that it can withstand significant compression without breaking. In determining the structural integrity and durability of various building materials, compressive strength is a crucial factor.
How much force can the femur withstand units per square inch?
The femur, the strongest bone in the human body, can withstand compressive forces of around 1,700 to 2,500 pounds-force per square inch (psi) before breaking.
What does mean concrete 3000 psi?
Concrete 3000 psi means that the concrete has a compressive strength of 3000 pounds per square inch (psi). This measurement indicates how much pressure the concrete can withstand before cracking or breaking. A higher psi value generally means stronger and more durable concrete.

Termused to describe material that can be pounded into shapes?
The term used to describe material that can be pounded into shapes is "malleable." This property is often associated with metals, such as gold and copper, which can be deformed under compressive stress without breaking. Malleability allows these materials to be shaped into thin sheets or various forms through processes like hammering or rolling.
What does it mean by hardness in tensile?
For metals, hardness is a measure of the deformation of a surface of the metal when subjected to a normal compressive force with a ball or other shape. Its units are arbitrary. Tensile strength is a measure of the maximum tensile load per unit of cross sectional area a material can withstand without breaking. Units are force/area.
The femur can withstand times the body weight without breaking?

Does malleability describe the ability of an object to break apart?
No, malleability does not describe the ability of an object to break apart; rather, it refers to the capacity of a material to be deformed or shaped under compressive stress without breaking. This property allows metals, for example, to be hammered or rolled into thin sheets. In contrast, brittleness describes a material's tendency to fracture or break when subjected to stress.
What is the meant by the term malleability?
Malleability refers to the ability of a material to be reshaped under compressive stress without breaking. Materials that are malleable can be easily hammered, rolled, or pressed into thin sheets without cracking or breaking.
How do they test for malleability on gold?
The gold malleability can be measured by how much pressure it can withstand without breaking.
Describe the microscopic features of osseous tissue that help long bones withstand lateral stress without breaking?
A lateral stress placed on a bone (e.g. on Nicole's left tibia and fibula) actually causes (A) compression of the bone on the side of impact and (B) stretching (tearing) on the side opposite of the impact.
In which factor does breaking stress depends?
Breaking stress of a material depends on factors such as the material's type, structure, temperature, and loading rate. It measures the maximum stress a material can withstand before breaking.
