During a car crash, the forearms of a passenger are slammed against the dashboard.
Each arm comes to rest from an initial speed of 80 km/h in 5 ms. If the arm has an effective
mass of 3 kg and bone material can withstand a maximum compression stress of 16 x 107
Pa,
will the arms withstand the crash? (cross-section of calcified area of the two forearm bones,
ulna and radius, is approximately 2.4 cm2
)
F = m (deltav/ deltat)
Deltav = 80 km/h × [1000 (m/km) / 3,600 (s/hr)] = 22.2 m/s
Delta t = 5 ms = 5 × 10-3
s
Delta F = 3 kg × [22.2 (m/s) / 5 × 10^-3
s] = 1.33 × 10^4

What is Bone has a Young's modulus under pressure?
Bone has a Young's modulus of about 18 x 109 Pa. Under compression, it can withstand a stress of about 160 x 106 Pa before breaking. Assume that the femur is 0.5 m long and calculate the amount of compression this bone can withstand without breaking. aB = Y EB = Y (deltaL / Lo) deltaL = (aB / Y) Lo here aB = 160 × 106 Pa; Y = 18 × 109 Pa deltaL = (160 × 106 Pa / 18 × 109 Pa) 0.5 m = 4.3 × 10-3 m = 4.3 mm
Is bone weaker under compression or tension forces?
Tension
How much pressure can bone withstand?
usually a lot of pressure but it depends on the bone. Example: It takes 12-16 pounds of pressure to break a knee.
What does piezoelectricity mean?
Piezoelectricity is the ability of some materials (notably crystals and certain ceramics , pincluding bone to generate an electric field or electric potential in response to applied mechanical stress. The effect is closely related to a change of polarization density within the material's volume. If the material is not short-circuited , the applied stress induces a voltage across the material. The word is derived from the Greek piezo or piezein, which means to squeeze or ress.
How is bone density test done?
A bone density test employs x-rays to measure the amount of calcium and other bone minerals are retained with the bone segment. A bone density test is used to diagnose osteoporosis.
How much force can a femur bone withstand?
A femur bone can withstand roughly 4000 N of force.
What type of bone is adapted to withstand stress?
Compact Bone
What is the type of bone that is adapted to withstand stresses that arrive from a limited range of directions?
Compact bones, which are dense, are bones adapted to withstand stresses. Compact bones are also referred to as cortical bone.
Which bone tissue is adapted to support weight and withstand tension strees?
Spongy bone

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.
The structure of bone tissue suits the function Which of the following bone tissues is adapted to support weight and withstand tension stress?
spongy bone^^WrongCOMPACT BONE
Does collagen make bone flexible?
Yes. Collagen is a mineral in your bone and marrow that makes your bones flexible yet strong enough to withstand a blow. :)The organic material in bone is collagen. This is a protein which forms long, flexible fibres in the matrix surrounding the bone cells. It is estimated that collagen makes up 25% of the total protein in the body.
How much weight can a cubic inch of bone withstand?
It depends on the bone. The femur (thigh bone) is much stringer than other bones.
The special material in bones that makes blood cells?
The bone marrow. As you look inside of a bone you will see a core of softer material. That material is bone marrow.
How does long bone resist breaking when stress?
How can a bone withstand 1000 pounds without breakng?
What is the function of the organic material in bone?
The organic material in bone, primarily collagen, provides flexibility and tensile strength, allowing bones to bend without breaking. It also helps in the repair and remodeling of bone tissue.
