2 CHAPTER 6. LAGRANGIAN MECHANICS 6.2 Hamilton’s Principle The equations of motion of classical mechanics are embodied in a variational principle, called Hamilton’s principle. Hamilton’s principle states that the motion of a system is such that the action functional S q(t) = Zt2 t1 dtL(q,q,t˙ ) (6.2) is an extremum, i.e. δS = 0.

Temperature coefficient of resistivity

Power Transmission Transmitting electrical power is done much more efficiently at higher voltages due to the desire to minimize (I2R) losses. Consider power transmission to a small community which is 100 mi from the power plant and which consumes power at a rate of 10 MW. In other words, the generating station needs to supply whatever power it ...

Experiment #1: RC Circuits

In more complicated circuits you will need to generalize the notions of series and parallel. For example, in Figure 2, the equivalent resistance of R 4 and R 5 in parallel, 1 R 4 1 R 5 1 R 4 * R 5 R 4 R 5 , is in series with R 3. 1.2 Ohm’s Law Ohm’s Law states that for a resistor the current and voltage are in phase and proportional. That ...

For unconsolidated materials (e.g. dry sand) the relationship between normal stress (σ n) and shear strength (S) is linear, passes through the origin: S = σ n tan φ 23 Compressive Strength!! For consolidated materials or cohesive soils, relationship also linear, but there is inherent shear strength due to interparticle bonding (cohesion - C):

Using these physical properties of the foundation materials the foundations may be designed to carry the loads from the structure with an adequate margin of safety. In doing this, much use may be made of soil mechanics but to a large extent foundation engineering still remains an art.
