Σελίδα 1 - A circle is a plane figure contained by one line, which is called the circumference, and is such that all straight lines drawn from a certain point within the figure to the circumference, are equal to one another.
Σελίδα 104 - The magnitude of the moment (generally called the moment) is the product of the magnitude of the force and the perpendicular distance of its line of action from the point or axis.
Σελίδα 67 - Cycloid. The cycloid is a curve generated by a point on the circumference of a circle which rolls on a straight line tangent to the circle.
Σελίδα 1 - A plane rectilineal angle is the inclination of two straight lines to one another, which meet together, but are not in the same straight line.
Σελίδα 20 - F') ; the diameter drawn through them is called the major axis, and the perpendicular bisector of this diameter the minor axis. It is also defined as the locus of a point which moves so that the ratio of its distance from a fixed point...
Σελίδα 107 - The Arm of a couple is the perpendicular distance between the lines of action of the two forces...
Σελίδα 107 - ... forces which tend to turn the body in the opposite direction about the same point.
Σελίδα 9 - Similar rectilineal figures are those which have their several angles equal, each to each, and the sides about the equal angles proportionals.
Σελίδα 182 - A parallelepiped is a prism whose bases are parallelograms. A pyramid is a polyhedron having a polygon for its base, and for its sides it has triangles which have a common vertex, and the sides of the polygon for their bases. The common vertex of the triangles is called the vertex, or apex, of the pyramid. The axis of a prism is a straight line joining the centres of its ends; and the axis of a pyramid is the straight line from its vertex to the centre of its base. A right prism or pyramid has its...
