The stiffness of bicycle frame made from new material should be compared to the stiffness of an aluminum frame. Concept introduction: The stiffness of any material depends on its elasticity. Elasticity is a property of any material through which it can be stretched from its regular shape or can become flexible. Any matter resumes its size after stretching through the help of its elasticity. The elasticity is different for different matters. The stiffness of any material is measured in modulus which is the ratio of stress to the strain for the material as: E = S t r e s s S t r a i n Higher the modulus more will be the stiffness of the material.

The stiffness of bicycle frame made from new material should be compared to the stiffness of an aluminum frame.
Concept introduction:
The stiffness of any material depends on its elasticity. Elasticity is a property of any material through which it can be stretched from its regular shape or can become flexible.
Any matter resumes its size after stretching through the help of its elasticity. The elasticity is different for different matters.
The stiffness of any material is measured in modulus which is the ratio of stress to the strain for the material as:
Higher the modulus more will be the stiffness of the material.
A chemistry grad student measures the performance of the new pump in his lab. The result is:
Z=19.1 kPa·mm3·s-1
conver Z to mJ·s-1
4. An alloy has an elastic modulus of 115 GPa. For the alloy, plastic deformation begins at a
stress of 275 MPa.
(a) If a sample of cross-sectional area 325 mm? is obtained from the alloy, determine the
maximum load that may be applied on the sample without plastic deformation.
(b) The original sample length is specified as 115 mm, what is the maximum length to
which the sample can be stretched without plastic deformation.
3. Is solid > liquid → gas an endothermic or exothermic process? Describe how this energy change
affects the energy of the molecules and their intermolecular forces.
