The First and Second Conditions for Equilibrium The first condition for equilibrium: The second condition for equilibrium: • • ΣF = 0 ΣΓ = 0 • In when both of these conditions are satisfied in static systems all forces and torques sum to zero. In problems where the first and second conditions of equilibrium are satisfied‚ the best strategy is to create FBD’s for both the first and second conditions‚ derive equations based on these FBD’s and then see what useful information may be gleaned from

HOW TO BE YOURSELF 1. Find yourself and define yourself on your terms Yet‚ you can’t be yourself if you don’t know‚ understand yourself first. It should be your primary goal to find this out. Find the time to dwell upon what you value and take time to consider what makes up the essence of who you are. As part of this‚ contemplate your life and choices. Try to think about what kinds of things you would or wouldn’t like to do‚ and act accordingly;

It was created to limit free thought‚ freedom‚ and self-expression. Newspeak is a metaphor of the total dominance of the state. 8.

Case in the news: Demand/Supply and Equilibrium This article is based on the fundamental idea of supply and demand of the iPhone 5 whose demand has outstripped its supply. Due to the fact that the demand is so high‚ even those who pre-ordered the new slim iPhone 5 had to wait until October to get this new phone. The sales have broken all previous records and stand tall at 2 million phones in the first 24 hours. According to the article people had been

Analytical and Equilibrium Molrity Analytical Molarity is the total number of a solute‚ regardless of its chemical state‚ in one liter of solution • describes how a solution is prepared(recipe) 98.0 g H2SO4 dissolved in water diluted to 1.0 L. 1.0 M H2SO4 Equilibrium Molarity or species molarity is the molar concentration of a particular specie in the solution. • requires a careful analysis on how solutes behave when it is dissolved in solvents 1.0 M H2SO4 (AM) 0.0 M H2SO4

Chemical equilibrium is the point at which the concentrations of reactants and products do not change with time. It would appear as if the reaction has stopped‚ but in fact‚ the rates of the forward and reverse reactions are equal‚ causing the reactants and products to be created at the same rate. This can be expressed mathematically in the form of the equilibrium constant. The following is the general equation for a reversible chemical reaction: aA+bB →cC+dD

PROBLEM SET 3 Problems for Chapter 3 1. Suppose the consumption function in the U.S. is represented by the following equation: C = 200 + .5 YD‚ where YD = Y – T and T = 200. a. What is the level of consumption in this economy if YD = 0? Briefly explain how individuals “pay for” this consumption when YD = 0. b. Given the above parameters‚ calculate the level of consumption if Y = 1200. Suppose Y increases to 1300. What happens to the level of YD as Y increases to 1300 (i.e. calculate

offspring have the same genotype ratio as their parents. This example was one of Hardy-Weinberg equilibrium. The next generation will express the same genotype ratio as their parents‚ and so on. But what exactly is needed to create Hardy-Weinberg equilibrium? (Basically‚ a population in Hardy-Weinberg equilibrium s not evolving in any way.) Five specific factors are needed to create Hardy-Weinberg equilibrium within a population- a very large population‚ isolation from other populations‚ no net mutations
