Webb24 maj 2024 · We can simplify this, using the small-angle approximations. The terms involving sin θ are fourth order in the small θ’s, so we can neglect them. Also, we can approximate cos θ by 1, because this entails dropping only terms of at least fourth order. So the top mass’s kinetic energy becomes 1 2 m r 2 ( 2 θ ˙ 1 − θ ˙ 2) 2 homework-and …
