A metre gauge train is moving at 72 kmph along a curved railway track of radius of curvature 500 m. Find the elevation of the outer rail above the inner rail so that there is no side thrust on the outer rail.
A railway locomotive enters a stretch of track, which is in the form of a circular arc of radius 280 m, at 10 m/s and with its speed increasing uniformly. Ten seconds into the stretch its speed is 14m/s and at 18s its speed is 19 m/s.Find (i) the magnitude of the locomotive’s linear acceleration when its speed is 14 m/s(ii) the direction of this acceleration at that point with respect to the locomotive’s radial acceleration (iii) the angular acceleration of the locomotive.
