m And so you lose your m, and so you see that y center of mass then becomes the square root of three divided by eight times l.
你失去了,得到了y轴质量中心,成了平方根,3除以8再乘l开方。
The period, which is 2 pi times the square root of l over g, if you substitute in your length of 5.1 meters, you will find 4.57 seconds.
周期,等于2π,乘以l/g的平方根,如果把长度为5。1米,代入,会得到4。57秒。
If I make it four times shorter-- l 2 the square root of four is two.
如果缩小4倍-,缩小4倍-,l,four,times,shorter--,4的平方根是。
