2. Determine the weight of a wrought-iron box girder 16 feet long, and of section shown—

3. A pump plunger, 17 inches diameter, arranged so as to deliver water on both up and down stroke, is attached to a crank shaft by a round two-inch rod. The crank is 10 inches deep, and makes 30 revolutions per minute. How long will it take to fill a circular tank 10 feet deep, whose diameter at bottom is 100 feet, the side slopes being 2 to 1?

DRAWING AND QUANTITY SURVEYING. The Board of Examiners.

Make a set of working drawings and prepare a bill of quantities of the factory chimney shown by the dimensioned sketch on the black-board.

PRINCIPAL DIMENSIONS.

Height, 150 feet.

Size of base, 15 feet square.
Height of base, 15 feet.

From 15 to 23 feet angles are gradually chamfered until at 23 feet the plan becomes octagonal and continues so to the top with a uniform batter. The top width measured over the sides of the octagon is 9 feet, and the thickness of the brickwork 9 inches for the top 25 feet and increasing 4 inches for every 25 feet downward.

MECHANICAL DRAWING AND DESCRIPTIVE GEOMETRY.

The Board of Examiners.

1. Describe the various instruments used for drawing circular curves, stating under what circumstances you would employ each, and what conditions you would expect a good instrument of each sort to comply with.

2. Show by a sketch how to arrange on one sheet of paper a side and end elevation, transverse section, and details of a simple structure, such as a small house, so as to secure clearness of delineation and minimize labour.

3. Give all the information you can as to practical methods of drawing the ellipse, parabola, hyperbola, and cycloid.

4. Make an isometrical and also a perspective drawing of the table at which you are seated. In the perspective drawing the eye should be 2 feet above the table and 3 feet to the right of its centre.

5. Discuss fully the various methods of constructing maps of the world.

APPLIED MECHANICS.

FIRST PAPER.

The Board of Examiners.

1. The stone pier of a bridge is 10 feet wide, and weighs 300 tons. At a point 20 feet above its base an arch meets it, exerting a thrust of 100 tons in a line inclined 45° to the horizontal. Find the centre of pressure at the base of the pier. Compute the maximum and minimum pressures per square foot on the foundation, and express your opinion as to its stability.

2. A rolled girder of 28-ton steel is 20 feet long, 10 inches deep, 5 inches wide, and inch thick, and is supported at both ends and at the centre. Compute the uniformly distributed load needed to break it, describe the position and mode of its fracture, and suggest a simple and cheap method of largely adding to its strength.

3. Determine graphically the modulus of section of a Tiron 6 inches deep, 4 inches wide, and inch thick.

4. The strength of beams, as determined by direct experiment, does not in all cases agree with the strength as deduced from the modulus of section and the tensile and compressive resistances of the material. Give all the information you can respecting this anomaly.

5. Determine the stresses in the girder shown on the black-board under a dead load of 2 tons on each upper panel point, plus a 15-ton steam roller whose wheel base is twice the panel length.

APPLIED MECHANICS.

SECOND PAPER.

The Board of Examiners.

1. Determine the stresses on the roof truss shown on the black-board.

2. A tension member in a bridge consists of two plates 9 inches by inch each. Design an economical rivetted joint for this member, and compute its efficiency.

3. Describe fully the method of proportioning and computing strength of the following connections in tension

(a) Eye and pin.
(b) Hook.

(c) Screw and nut.
(d) Cotter.

4. Discuss fully the state of stress in a cylindrical water tank with spherical bottom, the radius of the sphere being much larger than that of the cylinder, and the tank being supported at the junction of the sphere and cylinder.

5. Make a drawing and describe the action of the autographic apparatus on the University Testing Machine.

CIVIL ENGINEERING-PART I.

FIRST PAPER.

The Board of Examiners.

1. Show by a numerical example how you would compare the relative merits of a cheap but shortlived engineering structure, and one of a more costly but durable character.

2. Describe fully, with illustrative sketches, the method of driving a railway tunnel through a hill consisting of stiff clay, interspersed with bands of fissured rock.

3. Write an essay on piles and pile-driving, giving full information as to how to select and prepare the piles, and how to determine when they are sufficiently driven; and supply a neat sketch, with numerical particulars, of an ordinary piledriver worked by manual power.

4. Describe fully the appliances needed and mode of procedure in casting, inspecting, and testing ordinary water-pipes of moderate size.

5. Describe fully the appliances needed and the mode. of setting and dressing the stones and the precautions to secure sound work in a bluestone pier for an iron bridge 30 feet long, 6 feet wide, and 20 feet high. Give sketch plans of two successive courses, showing the bond you would employ.
