Not illustrated. 1908 Excerpt: ...12 g/cm3, in the form of a circular cylinder, is brought exactly under the sphere, with its axis vertical, and it is found that the apparent weight of the sphere is increased by 0 056 g. The diameter and height of the cylinder is 50 cm, and the distance between the surface of the cylinder and centre of the sphere is 50 cm. Calculate G and A, neglecting the action between the sphere and counterpoise. (4) Calculate the thrust due to the gravitation between two iron spheres 1 metre in diameter and of density 7-5 in contact on a smooth horizontal table. (5) Two small spheres are in contact with the upper and lower surface of a large horizontal slab of lead, of density 2A. Compare the difference in weight due to the attraction of the lead with that due to difference of altitude. (6) Two spheres of lead, each 1 metre in diameter, are placed a kilometre apart: prove that they will come into contact in about 463 days, taking the density of lead double the mean density of the Earth. (7) In a book, de Mundi Systemate, attributed to Newton, it is calculated that two spheres a foot in diameter, and of the same mean density as the Earth, starting J inch apart, would take a little less than a month to come into contact. Correct the calculation, and give the true result. (Poynting, p. 9.) (8) Prove that the parabolic velocity for a minor planet, 100 miles in diameter and of the same density as the Earth, is about 460 f/s; and calculate the value of g on the surface. Equations Of Motion Of A Body Referred To Co-ordinate Axes. 73. The motion of a point P (the C.G. of a projectile, for instance) is given by its coordinates x, y after time of flight t sees, such that OM = x, ON = y (fig. 59); we suppose Ox horizontal, Oy vertical, and OP the vertical elevation of the trajecto...
