5^F→ntust661:看你系統想看哪些02/22 20:03

7^F→ntust661:因為我取整體系統才會沒有受到系統外力作功02/22 20:05

9^F→ntust661:如果單取桿件就要考慮到外力力作功= =02/22 20:06

10^F→ntust661:如B大說的我指的外力作功就是桿件連接車子的支承力02/22 20:07

11^F→ntust661:有問題再繼續討論吧! 我先去泡茶喝= =...02/22 20:08

14^F→ntust661:取哪裏是喜好問題啦XD02/22 20:46

1^F推ntust661:雙自由度兩個governing equation02/22 18:39

2^F→ntust661:所以你要對兩種變數偏微分02/22 18:40

3^F→ntust661:衝量只有水平方向吧你碰撞的位置就只有垂直面而已~02/22 18:41

4^F→ntust661:要畫上垂直衝量也可以但算出來可能會為零吧?02/22 18:42

1^F推ntust661:如果沒給等速則加速度還會以一項~!02/20 23:57

3^F推ntust661:如果有加速度就是代表有效力圖要多畫一個 m*(ax) !02/21 00:01

4^F→ntust661:所以我在猜，V給你只是要跟你說桿子支承點加速度 = 002/21 00:02

8^F→ntust661:對!02/21 00:04

2^F推ntust661:X-Z平面代表法向量為 j02/18 20:51

3^F→ntust661:而 ▽f = ... i 方向等於零 , k 方向等於零得 (x,y,z)02/18 20:56

4^F→ntust661:然後帶入點就有解囉02/18 20:57
