اقرأ أكثرThe angle θ θ describes the position of the pendulum. Using the small angle approximation gives an approximate solution for small angles, d2θ dt2 = − g Lθ. (15.5.1) (15.5.1) d 2 θ d t 2 = − g L θ. Because this equation has the same form as the equation for SHM, the solution is easy to find. The angular frequency is.
اقرأ أكثرSection snippets Modelling. The system studied is shown in Fig. 1. A rotor of inertia J r rotates about its centre O.Its total angular position is ϑ (t) = Ω t + θ (t) where t is the time, Ω is the mean rotational velocity and θ (t) corresponds to the fluctuating part of the rotation. A torque T (ϑ) = T 0 + T θ (ϑ) is applied to the rotor where T 0 is its constant part …
