(5 marks) Write the equation of motion for the double pendulum system shown below. Assume that the displacement angles of the pendulum are small enough to ensure that the spring is always horizontal. The pendulum rods are taken to be massless, of length I, and the springs are 75% of the way down the rods. 3. k, m2
There is a double-pendulum system, each with mass m and length L, attached to a cart of mass M. The cart has linear position x, pendulum 1 has angular position θ, and pendulum 2 has angular position φ. The cart has a force, F, applied in the x-direction to the cart. m,L Using sum of forces, sum of moments, and constraint equations, determine the 12 equations 12 unknowns. Solve the system of equations for the 12 unknowns including the EOMs....
Fresh answer please. Thanks in advance.
Consider the following pendulum that consists of a massless straight rigid rod AOB with a point mass m attached at the top point B and a point massM attached at the bottom point A. The pendulum rotates without friction about point O and it is initially at vertical equilibrium. Two springs are attached at the top point B from one end and fixed at the other end. The springs are unstretched at t-0 and...

3. The motion of a 1DOF mass-spring-damper system (see Figure 1) is modeled by the following second order linear ODE: dx,2 dt n dt2 (0) C dt where is the damping ratio an wn is the natural frequency, both related to k, b, and m (the spring constant, damping coefficient, and mass, respectively) (a) Use the forward difference approximations of (b) Using Δt andd to obtain a finite difference formula for x(t+ 2Δ) (like we did in class for the...
Problem 1: For the system in figure (1-a), the spring attachment point B is given a horizontal motion Xp-b cos cut from the equilibrium position. The two springs have the same stiffness k 10 N/m and the damper has a damping coefficient c. Neglect the friction and mass associated with the pulleys. a) Determine the critical driving frequency for which the oscillations of the mass m tend to become excessively large. b) For a critically damped system, determine damping coefficient...
2. (35 points) A pendulum consists of a point mass (m) attached to the end of a spring (massless spring, equilibrium length-Lo and spring constant- k). The other end of the spring is attached to the ceiling. Initially the spring is un-sketched but is making an angle θ° with the vertical, the mass is released from rest, see figure below. Let the instantaneous length of the spring be r. Let the acceleration due to gravity be g celing (a) (10...
