3F→:你確定不是柱體間光滑,然後求三角形和地面的摩擦係數嗎?08/18 17:58
6F→:其實我推完就發現我錯了，地面光滑也是可行08/18 18:25
7F→:左邊三角形: 正向力往左下; 摩擦力往右下08/18 18:27
8F→:可以用水平方向靜力平衡來算08/18 18:27
16F→:我算答案是tan(theta), theta是地面和接觸面的夾角08/18 21:39
24F→:樓上你可以想想:將一斜面放在光滑地面08/18 23:15
25F→:斜面上有一物體質量為m，斜面和物體之間摩擦係數為mu08/18 23:16
26F→:和這題有甚麼不同? 地面光滑其實簡化了很多東西08/18 23:17
1F推:兩者都變長。a比b更長, 所以凹面向右08/18 04:38
