  • Part of the International Code Council's widely successful Code Commentary series, the 2009 International energy conservation Code Commentary will give readers the tools they need to master the regulations set forth by the 2009 International Energy Conservation Code (IECC). The comprehensive yet practical guide contains the full text of the code, its tables and figures, as well as valuable, in-depth commentaries. These commentaries aim to explore the full meaning of the code, its implications, and its real-world applications.

  • The rate of energy conversion or transmission (i.e. power) is related to the physical quantities such as force, speed, voltage, current, etc.For mechanical system, rate of energy transfer (i.e., power) to an object is the product of the force (F in Newton) and the speed (S in meter/sec) of the point where the force is applied.Q1. A person pushes an out-of-gas car with a force of 100 Newton (about 22.5 lb of force) to maintain a speed of 0.2 m/s. It took him 10 minutes to get to the nearest gas station. How much energy did this person use to do this work?...

  •  We knew that the concepts of mechanical work and energy play an important role in studying mechanical phenomena.  Concerning to thermal phenomena, there exits a new form of energy called “heat”: Heat can be transferred from one to other systems For a system with volume held constant, the effect of heat is to change the temparature of a system.

  • The first law of thermodynamics gives the quantiative relations between the internal energy of a system and the quantities of heat and work that the system exchange with surroundings. It express the conservation of energy. The first law of thermodynamics is true, but not enough ! Why ? Many thermodynamic processes which don’t violate the 1st law, but don’t happen in nature !

  • Electrical energy plays an important role in our daily life. It can universally be applied and easily be converted into light, heat or mechanical energy. A general problem, however, is that electrical energy can hardly be stored. Capacitors allow its direct storage, but the quantities are small, compared to the demand of most applications. In general, the storage of electrical energy requires its conversion into another form of energy.

  • The U.S. legal system is admired around the world for the freedoms it allows the individual and the fairness with which it attempts to treat all persons. On the surface, it may seem simple, yet those who have delved into it know that this system of federal and state constitutions, statutes, regulations, and common-law decisions is elaborate and complex. It derives from the English common law, but includes principles older than England, along with some principles from other lands. The U.S.

  • In July of 1994, Comet Shoemaker-Levy struck the planet Jupiter, depositing 7 × 1022 joules of energy, and incidentally giving rise to a series of Hollywood movies in which our own planet is threatened by an impact by a comet or asteroid. There is evidence that such an impact caused the extinction of the dinosaurs. Left: Jupiter’s gravitational force on the near side of the comet was greater than on the far side, and this difference in force tore up the comet into a string of fragments.

  • The boundless energy of youth often must give way to the laws of physics. All too often I’ve seen bright ideas flounder for a lack of fundamental knowledge. If this book can foster the development of the art, if it can encourage and educate the robotic community, if it can provide the missing ingredients—the secret sauce—then I did my job right. If you have a sense that a robot is more than wires and wheels, then this book is for you.
