Introduction This lesson will address questions related to different levels of government: How should various responsibilities be allocated to different levels of government? Is decentralized government decision making desirable? Are locally raised taxes a good way to pay for services provided locally?

In lecture D9, we saw the principle of impulse and momentum applied to particle motion. This principle was of particular importance when the applied forces were functions of time and when interactions between particles occurred over very short times, such as with impact forces. In this lecture, we extend these principles to two dimensional rigid body dynamics. Impulse and Momentum Equations Linear Momentum In lecture D18, we introduced the equations of motion for a two dimensional rigid body. The linear momen- tum for a system of particles is defined

In this lecture, we will revisit the principle of work and energy introduced in lecture D7 for particle dynamics, and extend it to 2D rigid body dynamics. Kinetic Energy for a 2D Rigid Body We start by recalling the kinetic energy expression for a system of particles derived in lecture D17

In this lecture, we will start from the general relative motion concepts introduced in lectures D11 and D12. and then apply them to describe the motion of 2D rigid bodies. We will think of a rigid body as a system of particles in which the distance between any two particles stays constant. The term 2-dimensional implies that particles move in parallel planes. This includes, for instance, a planar body moving within its plane

系统最优化分配按照 Wardrop第二法则,即使得路 网中总行驶时间最小进行交通量分配。 该方法适用于最大限度地使用现有道路系统的场 合。从径路选择角度,该分配方法与用户均衡分配法 中用户一直选择时间上的最短径路不同,它有必要让 用户选择最短径路以外的径路。从此种意义上说,是 道路规划者或道路管理者所希望的分配原则,尤其在 智能交通系统获得广泛应用之后
