Find the equation of motion of the uniform rigid bar $O A$ of length $l$ and mass $m$ shown in Fig. $2.104 .$ Also find its natural frequency.

Assume that the bar is rigid with a mass moment of inertia Jo = 6 kg m^2 and the mass m1 = 10 kg. Use the following values for the springs: k1 = 20000 N/m, k2 = 25000 N/m, k3 = 30000 N/m. Also, the torque constant kt = 3500 Nm/rad and the length of the bar L = 4m. Find the natural frequency of the system.

00:01 So for this problem, we're going to use the equation of motion, which is j -0, is equal to negative k -t minus k -1a times a minus k -2, l times l.
00:22 And so we know that j -0 is equal to 1 over 12, m -l squared, plus m -l -2 squared, and that's equal to a third, m l squared.
00:35 And so now you plug that in a third m l squared plus kt plus k1 a squared plus k2 times l and that's equivalent to zero and so w n is equal to three times t plus k1 a squared plus k l squared sorry k2 l squared divided by i .m...
