Сторінка 55 - The radius of gyration is the distance from the axis of rotation to the center of gyration.
Сторінка 49 - Show that the moment of inertia of a body about any axis is equal to the moment of inertia about a parallel axis through the center of mass plus the product of the mass of the body and the square of the distance between the axes.
Сторінка 138 - The thumb, forefinger, and middle finger of the left hand are held at right angles to each other ; then if the forefinger shows the direction of the lines of force, and the middle finger the direction of the current, the thumb will show the direction of motion.
Сторінка 242 - Divide the difference in temperature between that at which the room is to be kept and the coldest outside atmosphere, by the difference between the temperature of the steam pipes and that at which you wish to keep the room, and the quotient will be the square feet or fraction thereof of plate or pipe surface to each square foot of glass, or its equivalent in wall surface.
