英语翻译
two masses,m1 and m2,connected to each other and to a central post by cords,rotate about the post at frequency f (revolutions per second) on a frictionless horizontal surface at distances r1 and r2 from the post.derive an algebraic expression for the tension in each segment of the cord.

答案

m1、m2两个物体用绳绑在一起并绑在一定点上,一起绕着定点作频率为f的圆周运动,半径分别为r1、r2,在图中画出各段绳的张力
题很简单 图你自己画吧
