第二章:动态模型 1. 钟摆运动方程 问题描述:计算以下单摆运动在施加阶跃转矩 T e T_e Te后的角度运动方程。 采用牛顿第二定律计算: { T e r − m g sin θ ( t ) = d v ( t ) d t v ( t ) = ω ( t ) r ω ( t ) = d θ ( t ) d t 化简可得: T e − m g r sin θ ( t ) = m
Click on the picture of Carl Franklin at the right to see something pretty amazing. 单击右边的卡尔·富兰克林的图片,可以看到令人惊叹的东西。 It's Carl as a one-man-band playing piano, drums, bass and guitar, mixed together s
When the Aretha Franklin biopic Respect comes out (hopefully later this year), you can credit production designer Ina Mayhew for how it looks. It’s her job to create sets and designs that make th
