i have an assighnment using matlab its a pendulem ? any idiea
) The following 2 DOF system is given consisting of double pendulum, where θ_1,θ_2 represent the angles of the top and bottom joint respectively. The bottom joint has a lumped mass m and is connected to the top one through an unstrechable, massless, unyielding string of length l. A second string of the same properties carries a disk of mass m and diameter D=0.5l. The distance between the bottom joint and the center of the disk is equal to l. Assume that the angles of oscillations are very small.
