The radius of curvature of railway line at a place is 200 m. If the distance between the railsis1.6 m and the outer rail is raised by 0.08 m above the inner rail, the speed of the train for which there is no'side pressure on the railsis

A railway line is banked with an angle of 0.01 radians. The height of the outer rail over inner rail, if the distance between the two rails of 1.5m, will be

A railway track is banked for a speed v, by making the height of the outer rail h higher than that of the inner rail. If the distance between the rails is l and the radius of the curvature of the track is r, then

Find the angle of banking of a railway track of radius of curvature 250 m,if the optimum velocity of the train is 90 frac (km)(h) . Also find the elevation of the outer rail over the inner rail if the two tracks are 1.6m apart

A train is moving at 20 m//s on a railway track of radius of curvature 1600 m. If the distance between two tracks is1.8 m, then the elevation of the outer track above the inner track will be

The metro which has been recently inroduced in Mumbai, encounters a sharp turn between Andheri and Chakala. To avoid any derailing issues, the authorities thought of banking the rails.The turn is of a radius of 400 m and the maximum speed attained by Mumbai Metro is 72 km//hr . IF the distance between the rails is 1 m then through what height should the outer rail be raised?

A train has to negotiate a curve of radius 400m. The speed of the train is 72 km//hour . The horizontal distance is to be raised with respect to the inner radius by h. IF distances between rail is l=1 m, the value of h will be (g=10 m//s^2 )

A simple pendulum is suspended from the roof of a railway carriage. What angle does the string make with the vertical if the carriage travels at a constant speed of 72 km/h around a circular track of radius 100m? Take g=9.8 m//s^2 .

Two parallel rail tracks run north-south. Train A moves north with a speed of 54 km hr^-1 aned train B moves south with a speed of 90 km hr^-1 . What is the (i) velocity of B with respect to A ? (ii) velocity of ground with respect to A? (iii) velocity of a monkey running on the roof of 18 km//hr with respect to train A as observed by a man standing on the ground.

What is the resistance of one of the rails of a railway track 20 km long at 20^@ C? The cross section area of rail is 25 cm^2 and the rail is made of steel having resistivity at 20^@ C as made of steel having resistivity at 20^@ C as 6 xx 10^-8 Omega m.
