Transit Price Elasticities and Cross-Elasticities
5 Similarly, if the elasticity of transit ridership with respect to transit service hours is 1 5, a 10 increase in service hours would cause a 15 increase in ridership Economists use several terms to classify the relative magnitude of elasticity values Unit elasticity refers to an elasticity with an absolute value of 1 0, meaning that price
Cross-linked Polymers and Rubber Elasticity
Definition of Rubber Elasticity and Requirements • Definition of Rubber Elasticity: Very large deformability with complete recoverability • Molecular Requirements: – Material must consist of polymer chains Need to change conformation and extension under stress – Polymer chains must be highly flexible

(ii) Definition of the Market The narrower the definition of the good, the higher its elasticity measure The broader the definition of the good, the lower its elasticity measure e g alcohol v Guinness; cars v Ford Focus’ Definition of a market a key concept – relevant later in this course and in next years courses (iii) The Time Period
Elasticities of Demand and Supply: Today add elasticity and
Equivalent definition to elasticity of demand Price elasticity of supply Percentage change in quantity supplied Percentage change in quantity price = • If the price elasticity of supply is greater than 1, supply is elastic • The cases for price elasticity = or < 1 also have the same interpretation as for demand elasticity
15 MODULUS OF ELASTICITY
Chapter 15 –Modulus of Elasticity page 79 15 MODULUS OF ELASTICITY The modulus of elasticity (= Young’s modulus) E is a material property, that describes its stiffness and is therefore one of the most important properties of solid materials Mechanical deformation puts energy into a material The energy is stored elastically or dissipated

CONTRIBUTION TO THE ASSESSMENT OF DAMAGE IN AGING CONCRETE
Mechanical (SDT, tensile and compressive strengths and modulus of elasticity) and microscopic (DRI) tests were then performed on these samples at different expansion levels, in order to determine the optimal conditions enabling the effective diagnostic character through each tool
