Page 35 - An arc of a circle is any part of the circumference. A chord is a straight line joining the extremities of an arc. A segment is any part of a circle, bounded by an arc and its chord.
Page 162 - Width of combustion box in inches. P = Pitch of supporting bolts in inches. D = Distance between the girders from centre to centre in inches. L = Length of girder in feet. d = Depth of girder in inches. T = Thickness of girder in inches.
Page 35 - A circle is a plane figure bounded by a curved line called the circumference, every point of which is equally distant from a point within called the center, Fig.
Page 518 - It will be seen that the arms of the guide or leading frame g, g, g, g, are connected with the axes of the paddles by means of the cranks c, c, c, c ; and it should be here stated, that the length of the cranks c, from the centre of the crank pin to the centre of the paddle axle, should correspond exactly with the distance from the centre of the main axis a, to the centre of the guide or leading frame...
Page 277 - Fig. 49. We will solve this problem partly graphically and partly by calculation. The first step is to find how fast the crank pin D is moving. For one turn of the crank, D travels through a distance equal to the circumference of a circle whose radius is R, that is, a distance of 2'ffTi.
Page 35 - A diameter of a circle is a straight line drawn through the centre, and terminated both ways by the circumference.
