In this lecture, we consider the motion of a 3D rigid body. We shall see that in the general three dimensional case, the angular velocity of the body can change in magnitude as well as in direction, and, as a consequence, the motion is considerably more complicated than that in two dimensions. Rotation About a Fixed Point We consider first the simplified situation in which the 3D body moves in such a way that there is always a point, O, which is fixed. It is clear that, in this case, the path of any point in the rigid body which is at a

Structure Types of cost curves Fixed, variable and total cost functions Average fixed, average variable and average cost functions Marginal cost functions Marginal and variable cost functions Marginal and average cost functions Short run and long run cost curves

Characteristics of Bonds o Bonds pay fixed coupon ( interest) payments at fixed intervals(usually every 6 months)and pay the par value at maturity

Chapter 10 11 Rotational Motion About Fixed Axis Torque, Rotational Inertia and Law Work and Rotational Kinetic Energy Angular Momentum and Conservation of Angular Momentum

In this lab session, the cantilever and fixed-fixed beams will be mechanically tested to determ material and device performance characteristics. The structures will be mechanically loaded the corresponding deflection measured. From the load versus deflection curves, an effective

调试语句的形式如下: on<条件〉<中断续元入口 表示当指定条件的中断发生时,由中断 续元来进行处理。例如: on fixed overflow go to LA 每当发生定点溢出时,转向以LA为标号 的语句

Context Chapter 9 introduced the model of aggregate demand and supply. Chapter 10 developed the IS-LM model, the basis of the aggregate demand curve. In Chapter 11, we will use the IS-LM model to see how policies and shocks affect income and the interest rate in the short run when prices are fixed

Uints I. Basic listening practice 1. Script W: Why do some people stay in one job for life while others switch jobs from time to M: Some people want a fixed routine so that they dont have to adapt tot new circumstances over and over again, while others think variety is the spice of life Q: According to the dialog, why do some people stick to one job for life?

Why Cost Estimation? Critically important part of system design Too high- lose the contract award Too low-over-run cost plus contracts, company loss on fixed price contracts Trends Design to cost Cost as an independent variable
