MECHANICAL DRAWING AND DESCRIPTIVE GEOMETRY.

The Board of Examiners.

1. Two geared wheels, whose pitch-circles are 2 feet and 3 feet in diameter, are working into one another; there are 54 teeth in the larger wheel, and 36 in the smaller. Draw profiles to natural scale of two teeth of each wheel.

2. An observer, 5 feet in height, is standing on the floor of a room; and a rectangle, 6 feet by 3 feet, is drawn on the floor, with its nearest corner at a distance of 15 feet from him; the longer side is inclined at an angle of 30° to the line of sight, which passes through the near corner. Draw this object as it will appear to the observer when his eye is at a distance of 9 inches from the plane of the paper, which is supposed to be vertical.

3. Make an isometrical drawing of the model before you to a scale one-fourth natural size.
