1. ABSTRACT In this experiment‚ we will measure the stress and the strain in an elastic body‚ observe Hooke’s law and determine the modulus of elasticity of the material. Furthermore‚ the stiffness k of the rigid body is determined as well. 2. OBJECTIVE To measure the deformation (strain) in a truss member‚ determine the modulus of elasticity of the material involved and the stiffness of the rigid body. 3. THEORY As shown in figure one‚ the system consists of a truss member BG and a rigid

Price Elasticity of Gold Group name: In-Demand The general inverse relationship between price and demand is a key fundamental in economics. A rise in price is known to shrink demand and vice versa. However‚ another important factor in economics is the price elasticity of demand‚ which can be interpreted as the percentage change in demand relative to the percentage change in price. Basic goods tend to be of low elasticity‚ thus the change in price has little effect on demand‚ while luxury goods

In this essay we will take a look at the factors that influence the equilibrium position of a good in the market‚ and the changes occur to the price and output levels of the good. Equilibrium "The market equilibrium occurs at the price where consumer’s willing to demand is equal to firm’s willingness to supply" (Begg and Ward‚ 2007).
