Number 12.22. Please help me

coordinates u and v. Calculate the forces Q, and Q. Solve the co 12.22. Double Arwood machine: Consider a system of masses and pulleys as shown in Fig. P12.22. Masses m, and m, are suspended from a string of length I,; and m, of kngth l. Pulleys A and B are hung from the ends of a string of kength l, over a third fixed pul- ky C. Sa up Lagrange's equations, and find the accelerations and the tensions in the strings Find the acceleration if m, = m, m, = 2m, m3 and m, are suspended by a string = 3m, and m, = 4m. %3D %3D
