| 摘 要： | 在滑轮问题中，绳的张力并没有直接作用在滑轮上。分析定滑轮和动滑轮的转动，发现绳的张力是通过转化为摩擦力矩或支承力矩间接起作用的。并且在滑轮的转动中。摩擦力矩总是在发挥着作用。

| Abstract: | In the working of pulleys, the tension of the ropes does not act on the puLleys directly. In our analysis of the rotation of the fast pulley and movable pulley, we have found the tension just takes an indirect effect in this process after being converted into the form of a friction torque or supportive torque. What is more, the friction torque takes an effect all the way in the rotation of the pulleys. |
