The machine in which we proposed to embark, was a copper vessel, that would have been an exact cube of six feet, if the corners and edges had not been rounded off.

Not too much mechanical apparatuslet the imagination have some play; a cube may be shown by a model, but let the drawing upon the blackboard represent the cube; and if possible let Nature be the blackboard; spread your triangles upon land and sky.

To Liquid add Chicken stock to make 2 cups or Water to make 2 cups and 1 chicken bouillon cube.

The names of substances, if they be used in them as they should, can no more disturb moral than they do mathematical discourses; where, if the mathematician speaks of a cube or globe of gold, or of any other body, he has his clear, settled idea, which varies not, though it may by mistake be applied to a particular body to which it belongs not. 17.

per square inch; divide the product by 9,000, and extract the cube root of the quotient, which will be the proper thickness of the web of the crank when of malleable iron, supposing the web to be continued to the centre of the shaft.

per square inch on the piston by the square of the diameter of the cylinder in inches, and the length of the crank in inches, and extract the cube root of the product, which, multiplied by 0.08264, will be the diameter of the paddle shaft journal in inches when of malleable iron, whatever the pressure of the steam may be.

Q.What are the dimensions of the cross head? A.If the length of the cross head be taken at 1.4 times the diameter of the cylinder, the dimensions of the cross head will be as follows:the exterior diameter of the eye in the cross head for the reception of the piston rod, will be equal to the diameter of the hole, plus 0.02827 times the cube root of the pressure on the piston in lbs.

per square inch, multiplied by the diameter of the cylinder in inches; and the depth of the eye will be 0.0979 times the cube root of the pressure on the piston in lbs.

The thickness of the web at centre will be 0.0245 times the cube root of the pressure on the piston in lbs.

per square inch, multiplied by the diameter of the cylinder in inches; and the depth of web at centre will be 0.09178 times the cube root of the pressure on the piston in lbs.

A.The depth of gibs and cutters for attaching the piston rod to the cross head, is 0.0358 times the cube root of the pressure of the steam on the piston in lbs.

per square inch, multiplied by the diameter of the cylinder; and the thickness of the gibs and cutters is 0.007 times the cube root of the pressure on the piston in lbs.

A.The atmospheric resistance, no doubt, increases as the square of the velocity, and the power, therefore, necessary to overcome it will increase as the cube of the velocity, since in doubling the speed four times, the power must be expended in overcoming the atmospheric resistance in half the time.

The work done, however, by a stream of air or other fluid in a given time, will vary as the cube of the velocity; for if the velocity of a stream of air be doubled, there will not only be four times the pressure exerted per square foot, but twice the quantity of air will be employed; and in windmills, accordingly, it is found, that the work done varies nearly as the cube of the velocity of the wind.

A.The resistance experienced by vessels moving in water varies as the square of the velocity of their motion, or nearly so; and the power necessary to impart an increased velocity varies nearly as the cube of such increased velocity.

This coefficient was obtained by multiplying the cube of the velocity of the vessels experimented upon, in miles per hour, by the sectional area of the immersed midship section in square feet, and dividing by the numbers of nominal horses power, and this coefficient will be large in the proportion of the goodness of the shape of the vessel.

If the speed of the Fairy herself had to be increased to 22.29 knots, the power would have to be increased in the proportion of the cube of 13 to the cube of 22.49, or 5.2 times, which makes the power necessary to propel the Fairy at that speed equal to 624 nominal horses power.

If the speed of the Fairy herself had to be increased to 22.29 knots, the power would have to be increased in the proportion of the cube of 13 to the cube of 22.49, or 5.2 times, which makes the power necessary to propel the Fairy at that speed equal to 624 nominal horses power.

A.The increase would be in the proportion of the cube root of 1 to the cube root of 2, or it would be 1.25 times greater.

A.The increase would be in the proportion of the cube root of 1 to the cube root of 2, or it would be 1.25 times greater.

We found ourselves in a square caverna perfect cube it looked likeabout thirty feet wide each way.

Following them, there comes, for American uses, the process of refining, of removing the so-called impurities and foreign substances, and the final production of sugar in the shape of white crystals of different size, of sugar as powdered, cube, loaf, or other form.

Though it is hard to define what are the social differences expressed by the large quadrangles of Francesco Sforza's hospital at Milan, and the heavy cube of the Riccardi palace at Florence, we feel that the genius loci has in each case controlled the architect.

Assuming the power required to vary as the cube of the speed, if 6,000 horsepower gave 14 knots, then about 4,800 would give 13 knotssay 5,000 horse power.
