用实验方法研究了颗粒物质与探测棒之间的最大静摩擦力。
The article reports experiments which show that the maximum static friction force F on the surface of an aluminum rod inserted in the dry granular.
啊哈，这我会做了，最大静摩擦方向斜向上-，大小相等，方向相反。
Aha! If that's the case, I know - that the maximum force is now pointing upwards — the same magnitude, but it has now a different direction.
而T又等于,因此m2g=m1gsinα,最大静摩擦力，也就是上面这个。
m2g Now, I know what T is, that is, m2 g + so m2 g equals m1 g sine alpha plus the maximum frictional force, which is this value.
