In the appendix to this chapter we show that this solution can be written in terms of elliptic integrals and derive corrections to formula for the period of a pendulum. At the end of this chapter, you will be able to do the following. apply the modeling process to a simple mechanical system, the nonlinear pendulum. use newton’s law to derive a differential equation for the dynamics of the pendulum. combine variables and parameters into dimensionless quantities. As the expressions for n 1 and !n 1 imply, this method is accurate up to 2nd order in time. to use this method, initial conditions 0, !0, and t0 must be defined. this method was used in exercises 1, 2 and 3 to approximate the motion of an undamped, undriven pendulum.

Simple and exact solutions of nonlinear pendulum are derived for all three classes of motion: swinging, stopping, and spinning. the maximum angular speed, ω m, occurs when the pendulum is at the bottom, and determines the class of nonlinear motion of the pendulum. Above you see a free body diagram of the pendulum where the force of gravity has been split up in a component tangent to displacement and a component perpendicular to it. M. peet lecture 3: control systems 6 21 linear approximation we can use the tangent to approximate a nonlinear function near a point x 0. key point: the approximation is tangent to the function at the point x 0. f(x) ˘=ax b the slope is given by a= d dx f(x)j x=x. We wish to find the period of oscillation of the pendulum from this diferential equation. we note from the initial conditions the pendulum is at an angle θ = θ0 and at some (later) time, we must have θ = 0 when it passes the lowest point of its arc (we must now assume θ0 > 0).
