PROBLEMS. Examiner--MR. JOHN Eliot, M. A. 1. A railway train of given mass is travelling due south at a uni. form rate along a line which runs due north and south. Prove that (supposing the earth perfectly spherical) the train will exert a strain on the metal rails towards the east the magnitude of which varies as the product of the velocity of the train and the sine of the latitude of the position, and a strain towards the south the magnitude of which varies as the sine of twice the latitude.
