Question

A railway carriage has its center of gravity (CG) at a height of 1m
above the rails which are 1m apart Calculate the maximum safe speed
at which it can travel round on unbanked curve of radius 80 m

Maximum safe speed,
v=rgtanθWher θ is the angle that CG makes with rails
So, tanθ=height of CG12×rail's sepration=2⇒v=rg2=80×9
82=19 8 m/s
