Unformatted text preview: 4. The motion of an animal in the horizontal plane can be represented by a simple rigid body springmass model, as shown below. Considering that such an animal is actually bipedal, construct the equations of motion, using Lagrange’s equations, that govern the motion of the system when the left leg is down. Use ζ,ψ, θ as the generalized coordinates and use the law of cosines to express the spring length η in terms of the other variables. See figure on next page…...
