Page 74 - ... with the vertical. It is lowered by means of two ropes passing under the barrel, one end of each rope being fixed, while two men pay out the other ends of the ropes. What pull in Ibs. must each man exert in order that the barrel may be supported at any point J (S.
Page 200 - Every body continues in its state of rest, or uniform motion in a straight line, except in so far as it may be compelled by force to change that state.
Page 205 - State the rule for finding the amount of work stored up in a given weight when moving with a given velocity. A weight of 6 cwt. moves with a velocity of 20 feet per second ; how many units of work are stored up in it 1 Ans.
Page 217 - The linear or the circular distance from the centre of one tooth to the centre of the next...
Page 2 - Thus when it is said that the sum of the three angles of any triangle is equal to two right angles, this is a theorem, the truth of which is demonstrated by Geometry.
Page 280 - The pulley on an engine shaft is 5 feet in diameter, and it makes 100 revolutions per minute. The motion is transmitted from this pulley to the main shaft by a belt running on a pulley, and the difference in tension between the tight and slack sides of the belt is 1 15 Ibs.
Page 201 - ... whether these arise from friction, cohesion, weight, or acceleration, action and reaction, in all combinations of machines, will be equal and opposite.
Page 242 - Refer to the figures in Lecture XVI. of the foot-driving gear for the screw-cutting lathe, before answering this question.] 14. When an ordinary train of wheels is employed for obtaining an Increased speed of rotation, how are the wheels arranged? Sketch an arrangement of four pulleys with bands for driving a fan at 1500 revolutions per minute from a shaft making 100 revolutions per minute. (S. and A. Exam. 1893.) 15.
Page 279 - What must be the width of the belt so that its greatest tension shall be 70 Ibs. per inch of width, it being assumed that the tension in the driving side is twice that in the slack side ? (Take ir = 3}.) Ans.
