What are the conditions which modify the putrefactive process? 4. What are the causes of sudden death, other than violence? 5. Specify all the tests proper to be employed in the examination of a stain supposed to be blood. 6. Describe the procession of symptoms and postmortem appearances in a case of poisoning by caustic ammonia by swallowing and by inhalation. 7. Mention all the animal irritant poisons, their symptoms, post-mortem appearances, and their antidotes. HONOUR EXAMINATION IN ENGINEERING. ADVANCED SURVEYING. The Board of Examiners. 1. Explain carefully how you would choose sites for fords, ferries, and bridges, in laying out lines of road. Under what circumstances is each of the above modes of crossing a stream applicable? Illustrate your answer by reference to actual cases. 2. Why is it that reverse curves having a common tangent point are objectionable on railways? What expedient would you adopt to obviate the evil? 3. It is required to set out a connection, consisting of a straight line and a curve of given radius, between two existing concentric lines of railway. State all necessary formulæ, and describe in their proper order the various operations needed. both in the office and in the field. 4. A suburban railway has stations 40 chains apart. Calculate the engine power required, and also the brake power, in order that a train of 100 tons gross weight may attain a speed of 30 miles per hour at 15 chains from the starting point, and maintain it until within 15 chains of its destination (a) when the line is level; (b) when the line falls 30 feet in the first 15 chains, then is level for 10 chains, then rises 30 feet in the last 15 chains. 5. By what considerations would you be guided in choosing the site for a large storage reservoir for domestic supply? 6. What is the best form for the cross section of a water channel to discharge 50 million gallons. per day, with a fall of 1 foot per mile, and what should be its dimensions if lined with smooth cement? 7. What are inverted syphons? Under what circumstances should they be used, how should they be located, and how do you calculate their discharge? 8. What instruments and tables do you need in order to determine the meridian by a single observation of a known star, and what special precautions are advisable against instrumental and othererrors ? 9. Describe the construction and mode of using base-line measuring apparatus in large trigonometrical surveys. MECHANICAL DRAWING AND DESCRIPTIVE GEOMETRY. The Board of Examiners. 1. A circle, 2 inches diameter, rolls along the circumference of a circle 4 inches diameter. Draw the curve traced in one complete revolution by a point in the circumference of the smaller circle(a) when it rolls inside the larger circle. (b) when it rolls outside. 2. A right square pyramid, having its base 3 inches square, and its height 5 inches, stands on a horizontal plane. Determine Determine the projection upon a vertical plane and the true form of a section made by an oblique plane inclined 45° to the vertical plane and cutting the axis of the pyramid 3 inches above its base. 3. Make an isometrical drawing of an ordinary examination table, with a cylinder 1 foot in diameter and 1 foot high placed symmetrically upon it, and surmounted by a 6-inch cube, also symmetrically placed. 4. Make a perspective drawing of the group of objects described in the last question, the point of sight being 6 inches above the top of the cube, and 2 feet distant horizontally from the axis of the cylinder. 5. Make a side elevation, plan, and section through cylinder and slide-valve of a horizontal steamengine of simple form. N.B.-Credit will be given for neatness and accuracy in drawing. The construction should in all cases be clearly shown. APPLIED MECHANICS. The Board of Examiners. 1. A factory chimney is square in plan and of the following dimensions:Height, 100 feet. Width of base, 10 feet. Thickness, 9 inches for 25 feet from the top, 13 inches for the next 25 feet, 18 inches for the next, and 22 inches for the bottom 25 feet. The material is brick, weighing 120 lbs. per cubic foot. Compute the pressure per square foot of wind at right angles to one side of the square at which the centre of pressure will coincide with the edge of the middle third of the base, and compare this with the calculated overturning pressure of railway carriages and tall trestle viaducts of modern design. 2. Make a sketch of one of the girders of the bridge over the Merri Creek at St. George's Road, and determine graphically the stress on each part |
