important points of this system of electric traction must be described. 

 If the railway is straight the speed may reach 2 metres (6 ft. 6 in.) 

 a second. But this is not generally the case. A system often 

 contains very sharp curves, in which the car and the suspended bin

ought to have a much lower speed than that given above. It will 

 be seen that the centre of the system in motion being much lower 

 than the railway on which it rolls, centrifugal force corresponding 

 to the speed of 2 metres per second would cause the system to 

 deviate appreciably from the vertical, which might cause mishaps.
