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.

而T又等于,因此m2g=m1gsinα,最大静摩擦力，也就是上面这个。

So this one equals m1 g cosine alpha - and this one, the x component-- which is in the minus x direction now-- equals m1 g sine alpha.

得到m1gcosα,而x方向上-,这里是x负方向-,大小是m1gsinα
