Page 35 - A sector, is any part of a circle bounded by an arc, and two radii, drawn to its extremities. A quadrant, or quarter of a circle, is a sector having a quarter part of the circumference for its arc, and the two radii perpendicular to each other.
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 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 190 - Iron bolts, case-hardened, bore a less breaking strain than when wholly iron, owing to the superior tenacity of the small proportion of steel being more than counterbalanced by the greater ductility of the remaining portion of iron.
