after being distorted. Elastic Limit: The maximum amounts by which an object or a material can be stretched and still regain its original shape after the distorting forces are removed. An object or a material which returns to its original length or size after being distorted suffers elastic deformation‚ i.e. it behaves within the elastic limit. Plastic deformation occurs when a material is deformed beyond its elastic limit. Stress and Strain The elastic properties of solids

Determinants of Price Elasticity of Demand Computing the Price Elasticity of Demand Demand tends to be more elastic : The price elasticity of demand is computed as the percentage change in the quantity demanded divided by the percentage change in price. if the good is a luxury. the longer the time period. the larger the number of close substitutes. the

= 0‚ we say that the we have a perfectly inelastic demand if −1 < if if D D D < 0;‚ we say that we have an inelastic demand = −1‚ we say that the we have a unitary elastic demand = −∞‚ we say that the we have a perfectly elastic demand if −∞ < D < −1 we say that the we have an elastic demand Example Suppose the price is initially $5.00‚ and the corresponding quantity demanded is 1‚000 units. Also suppose‚ that when the price rises

What is the difference between pressure and stress? Answer: Pressure is the external force acting over a unit surface area of a material. Stress is an internal force acting over a cross sectional area within the material. It may also be thought of as the internal resistive response of a material to the applied external pressure. They both have the units of force / area. suppose we have a cubical solid mass. We apply external force of few magnitude on it and this force will try to deform the

increases. Conversely‚ a price increase of a good or service that is considered less of a necessity will deter more consumers because the opportunity cost of buying the product will become too high. A good or service is considered to be highly elastic if a slight change in price leads to a sharp change in the quantity demanded or supplied. Usually these kinds of products are readily available in the market and a person may not necessarily need them in his or her daily life. On the other hand‚ an

conservation of momentum in collisions using two bodies. We also calculated the amount of kinetic energy in elastic and inelastic collisions before and after the collision. Introduction: When bodies collide with each other‚ the total momentum p = mv‚ is always conserved regardless of the type of collision provided no external forces are present. There are two types of collisions. In an elastic collision‚ both the kinetic energy and the momentum are conserved. An inelastic collision is one in which

Romar M. Cabinta EXERCISES 15 WORK‚ ENERGY‚ AND POWER A. CONCEPTUAL QUESTIONS 1. Is work done when you move a book from the top of the desk to the floor? Why? Yes. It is because the displacement of the book from the top of the desk to the floor and the force that is applied to the book is parallel with one another. 2. State the law of Conservation of Mechanical Energy in two ways? The law of conservation of energy states that energy may neither be created nor destroyed.
