Common terms and phrases

Popular passages

Page 69 - A solid immersed in a liquid is buoyed up by a force equal to the weight of the liquid displaced.
Page 70 - ... the ratio of the ovendry weight of a sample to the weight of a volume of water equal to the volume of the sample at some specific moisture content, as green, air-dry, or ovendry.
Page 14 - Newton's first law of motion: " Every body continues in its state of rest or uniform motion in a straight line, except in so far as it is compelled to change that state by a force impressed upon it.
Page 158 - ... subjected to the action of a periodic force that varies as an harmonic function of the time, we have the conditions necessary for a forced vibration. The ensuing motion is the response of the system to the impressed, external force, and continues so long as the force continues. Examples of forced vibration are seen in the motion of the pendulum of a clock or the balance wheel of a watch, in the vibration of a tuning fork driven by an electric current, or of the sounding board of a piano or body...
Page 182 - ... the ratio between the sine of the angle of incidence and the sine of the angle of refraction is a constant, depending only upon the nature of the two media.
Page 4 - In the system in common use among scientific men the unit of length is the centimeter, the unit of mass is the gram and the unit of time is the second. This is usually called the c.
Page 94 - Plateau will remember that when two spherules of oliveoil, suspended in a mixture of alcohol and water of the same density as the oil, are brought together, they do not immediately unite. Something like a pellicle...
Page 40 - The moment of a force about any point is the product of the magnitude of the force and the perpendicular distance from the point to the line of action of the force.
