To investigate the relationship between load‚ span width‚ height (depth) and deflection of a simply supported beam. 2. To ascertain the Coefficient of Elasticity (Young’s Modulus) for steel‚ brass and aluminium.

of materials. What material property defines each of these characteristics? Problem 3: In the diagram above‚ identify the elastic and plastic regions‚ estimate the Modulus of Elasticity‚ the Ultimate Tensile Strength‚ the Yield Strength and the fracture strain. Problem 4: A student reads that the Young’s modulus of elasticity for cast iron is 2.1x1011 Pa and that the cast iron fails abruptly when a strain of 0.0005 is reached. From this information‚ what would be the stress needed to break the specimen

CASE STUDY ON INDIAN RAILWAYS (MONOPOLY) In economics‚ a monopoly (from the Latin word monopolium – Greek language monos‚ one + polein‚ to sell) is defined as a persistent market situation where there is only one provider of a product or service. Monopolies are characterized by a lack of economic competition for the good or service that they provide and a lack of viable substitute goods. Monopoly should be distinguished from monopsony‚ in which there is only one buyer of the product or service;

To increase profit the monopolist should: (a) Increase price and sell less X (b) Increase price and sell more (c) Decrease price and sell less (d)

Include the four (4) elements of the economic way of thinking in your analysis It is a real case of negative externalities both in consumption and production. production of alcohol causes pollution too.

buyers’ (Layton‚ Robinson & Tucker 2005). It depends on both elasticities of demand and supply. In economic‚ compulsory levy a higher tax for alcopops is a good way to correct for negative externalities associated with excessive consumption of alcopops. If the government imposed a $100 per 1‚000 litres excise tax on suppliers of the alcopos over all price ranges‚ both suppliers and consumers share burden of tax. On account of the elasticity of demand for alcopops use is inelastic‚ consumers would bear

thickness and material are investigated. It is found that the deflection of the beam changes linearly with the load and as the beam thickness increases‚ the beam deflection decreases. In addition‚ since different materials have different modulus of elasticity‚ deflection of different materials under a specific load is different. Depending on the results of the experiment‚ it is observed that the measured deflection values under different loads and for different materials overlap the Euler-Bernoulli Beam

Hardness Tester. The second process was bend beam testing. This test was performed to determine and compare the Modulus of Elasticity‚ Yield Strength and Yield Strain on four different materials using a cantilever beam and vernier calipers. Background -Plastic Deformation- When a material is permanently deformed after a force is applied then removed. -Modulus of Elasticity- Describes the materials properties to be deformed elastically/non-permanently. This is the slope of the stress-strain curve

What is the estimated price elasticity of demand for home heating oil? |(-2) Phho/Q |= 2 (1.2/6.6)=0.364 D. If the sellers of home heating oil are profit maximizers‚ how should price be adjusted? From the information we have we cannot determine is price should be changed. Point Price Elasticity is less than 1 in absolute value so revenues can be increased by raising price. Therefore the company might want to experiment
