QUESTION 1 Why would an engineer be interested in yield strength of a material for a particular application? In civil engineering‚ an engineer should always be concerned in yield strength of a material for a particular application. Yield strength is defined as the point where materials begin to deform plastically. Before the prior of yield strength the materials deform elastically and will return to its original shape when the applied stress is removed. The knowledge of this is important for engineers

Topic 6 - The Theory of Consumer Behavior – the theory of utility • The theory of consumer behaviour may be analysed by either utility theory and / or indifference curve analysis. • Note: this course only requires students to be aware of utility theory. Indifference curve analysis is undertaken in year 2 and is not a requirement of this course Basic Principles of the theory of Consumer Behaviour • Consumers are rational optimisers • Consumers seek to maximise total utility • Utility is achieved

spacing on the growth and yield of potato (var. Diamant). Different nitrogen levels viz. 0‚ 127.0‚ 190.5 and 254.0 kg N/ha significantly influenced plant height‚ foliage coverage‚ number of main stem per hill‚ days required for 80% maturity of the crop‚ fresh weight of haulm (g/hill)‚ number of tubers per hill‚ weight of tubers per hill‚ total yield of tubers per hectare and yield of seed and non-seed tubers per hectare. Application of 254.0 kg N/ha gave the highest yield of tubers (24.33 t/ha) and

Indifference Curve - An indifference curve is a graph showing combination of two goods that give the consumer equal satisfaction and utility. Definition: An indifference curve is a graph showing combination of two goods that give the consumer equal satisfaction and utility. Each point on an indifference curve indicates that a consumer is indifferent between the two and all points give him the same utility. Description: Graphically‚ the indifference curve is drawn as a

NS 10.5 (pg 1 of 2) Heating and Cooling Curves What happens when we heat a sample of ice that is initially at -15°C? The addition of heat causes the temperature of the ice to increase. As long as the temperature is below 0°C‚ the sample remains frozen. When the temperature reaches 0°C (the melting point of water)‚ the ice begins to melt. Because melting is an endothermic process‚ the heat we add at 0°C is used to convert ice to water and the temperature remains constant until all the ice

variable cost curve. Average variable cost curve is a curve that graphically represents the relation between average variable cost incurred by a firm in the short-run production of a good or service and the quantity produced. This curve is constructed to capture the relation between average variable cost and the level of output‚ holding other variables‚ like technology and resource prices‚ constant. The AVC curve is ‘U’ shaped because the falling portion of the AVC curve reflects an

If supply curve shifts‚ how it is going to affect the market equilibrium. How market will resettle to the new equilibrium?? Changes in price result in movement along the supply curve‚ changes in other relevant factors cause a shift in supply‚ a shift of the supply curve to the left or right such a shift results in a change in quantity supplied for a given price level. If the change causes an increase in the quantity supplied at each price level. If the change causes an increase in the quantity
