Σελίδα 16 - If any number of forces, acting at a point, can be represented in magnitude and direction by the sides of a polygon taken in order, they will be in equilibrium.
Σελίδα 10 - If two forces acting at a point be represented in magnitude and direction by two straight lines drawn from that point, and if a parallelogram be constructed having these two lines for adjacent sides, then that diagonal of the parallelogram which passes through the point of application of the forces will represent their resultant in magnitude and direction.
Σελίδα 68 - MB 1871. 36. A body is projected up an inclined plane with given velocity. Show that the space described in any time is equal to that which would be described in the same time with a uniform velocity equal to half the sum of the velocities at the beginning and end of the time. Hence find the space described on a plane inclined at 30° to the horizon while the velocity changes from 48 to 16 ft. per see.
Σελίδα 12 - ... one of them is equal and opposite to the resultant of the other two.
Σελίδα 23 - couple about any point in the plane of the couple is equal to the algebraic sum of the moments of the two forces composing the couple about the same point.
Σελίδα 24 - The bending moment at any Imaginary transverse section of a beam Is equal to the algebraic sum of the moments of all the forces to either side of the section. bending of strata (Geol.).
Σελίδα 21 - The moment of the resultant force, or resultant couple, of any system of coplanar forces about any point in their plane is equal to the algebraic sum of the separate moments of the forces composing the system about the same point.
Σελίδα 20 - ... to any point in the plane of the forces, is equal to the sum...
Σελίδα 77 - ... g is the same for all bodies at the same place on the earth's surface.
