what is the difference between tensile and compressive strength of bone? explain
Tensile is increase in the length of the material or object in general and compressive means the decrease in the length. The bones in the body is made up of material with tensile strength which brings about the fracture toughness and structural material that's not good. The tensile contains the inorganic salts, calcium carbonate and collagen fibers. The process of calcification occurs only with presence of collagen fibers. Minerals hardens the bones and collagen provide softness tensility of the bone.
The compressive strength of bone is were the bone is formed in such a way to compress and not be tensile for instance covering of brain, vertebra, heart lungs which protects the internal organs.

(a) What is meant by the terms strength and toughness? Describe the difference between yield strength and ultimate tensile strength, highlighting how they might be determined [6 marks] (b) If a torque of loo kNm is applied to a solid circular shaft of 150mm diameter, what is the maximum shearing stress generated within in material? (e) Where is this stress located with respect to the shaft?
A reinforced concrete beam has a 28 day compressive strength of 5 ksi. What is the tensile strain that corresponds to cracking in the beam?
An engineer studying the tensile strength of a composite material knows that tensile strength is approximately normally distributed with σ = 60 psi. A random sample of 20 specimens has a mean tensile strength of 3450 psi. (a) Test the hypothesis that the mean tensile strength is 3500 psi, using α = 0.01 (b) What is the smallest level of significance at which you would be willing to reject the null hypothesis? (c) What is the β error for the...
The shaft of the tibia is subjected to compressive forces. The length of the tibia shaft is 0.30 m and the cross-sectional area of cortical bone in the shaft is 0.0002 m2. If the ultimate strength of cortical bone is 200 x 10^6 N/m2 and if the elastic modulus of the shaft of the tibia is 2 x 10^10 N/m2, what is the maximum compressive force (in N) that can be applied to the tibia shaft before compressive failure? Now...
4. Compressive strength testing performed on a concrete specimen at 28 days revealed a failure load of 90000 lb. Split tensile testing had a failure load of 22500 lb. The specimen is cylindrical with a 4" diameter and 8" length. Calculate the following: a. Con.pressive strength b. Tensile strength c. Moduli of rupture and elasticity.
Consider a study to determine the compressive strength of concrete blocks used for paving Two methods of manufacturing concrete blocks are under investigation-method 1 (which is more expensive) and method 2. Research indicates that the greater the compressive strength of concrete, the greater the durability of a concrete block. Therefore the question is which if either, of the two methods produces greater compressive strength. In addition, the manufacturer considers that an average difference between the methods of less than 500...
