Σελίδα 282 - The circumference of every circle is supposed to be divided into 360 equal parts, called degrees ; each degree into 60 equal parts, called minutes ; and each minute into 60 equal parts, called seconds.
Σελίδα 136 - Change of motion is proportional to the impressed force, and takes place in the direction of the straight line in which the force is impressed.
Σελίδα 114 - A force is said to do work when its point of application moves in the direction of the force.
Σελίδα 177 - Let the particle be projected from a point P with velocity u in a direction making an angle a with the horizon ; also let PAP...
Σελίδα 169 - If a moving point possess simultaneously velocities which are represented in magnitude and direction by the two sides of a parallelogram drawn from a point, they are equivalent to a velocity which is represented in magnitude and direction by the diagonal of the parallelogram passing through the point.
Σελίδα 181 - As a simple example consider the case of a particle tied to one end of a string, the other end of which is attached to a point of a smooth horizontal table.
Σελίδα 45 - The Arm of a couple is the perpendicular distance between the lines of action of the two forces...
Σελίδα 110 - Hence we see that the coefficient of friction is equal to the tangent of the angle of friction.
