To solve these 2ndorder ODEs in MotionGenesis™, type
Constant g = 9.8 m/s^2 % Earth's gravitational acceleration
Specified L'' % Cable length (changes with time)
SetDt( L = 50  2*t ) % Set L = 502*t, L' = 2, L'' = 0
Variable theta'' = (2*L'*theta'  g*sin(theta))/L
To Input initial values and numerical integration parameters, type
Input theta = 1 deg, theta' = 0 deg/sec
Input tFinal = 24.92 sec, tStep = 0.02 sec
