有这样一道题:如图1所示,有一质量为m、半径为R的圃环绕中心在其所在平面内以角速度ω匀速转动.已知环不受任何外力,求环的张力.用微元法求解:在环上取一小段作为研究对象,根据牛顿第二定律列式计
There is such a question: As shown in Figure 1, a garden with a mass of m and a radius of R surrounds the center in its plane at an angular velocity of ω. The known ring is free from any external force and seeks the tension of the ring. Method Solving: Take a small segment on the ring as a research object, according to Newton’s second law
