Σελίδα 83 - If three forces acting at a point be represented in magnitude and direction by the sides of a triangle taken in order, they will be in equilibrium.
Σελίδα 50 - Thus a parabola is the locus of a point which moves so that its distance from a fixed point is equal to its distance from a fixed straight line (see fig.
Σελίδα 93 - Change of motion is proportional to the impressed force and takes place in the direction of the straight line in which the force acts.
Σελίδα 30 - The unit of circular measure is the angle subtended at the centre of a circle by an arc equal in length to the radius.
Σελίδα 93 - Every body continues in its state of rest or of uniform motion in a straight line, except in so far as it may be compelled by impressed forces to change that state.
Σελίδα 83 - The Parallelogram of Forces.— If two forces acting at a point be represented in magnitude and direction by the...
Σελίδα 84 - The Moment of a Force about a point is the product of the Force by the perpendicular distance of the point from the line of action of the force.
Σελίδα 10 - Worth of a debt, payable at a future time without interest, is such a sum as, being put at legal interest, will amount to the given debt when it becomes due.
Σελίδα 20 - One quantity is said to vary directly as a second and inversely as a third, when it varies jointly as the second and the reciprocal of the third. Thus...
