Termehu Dievskaya VA task 2 task Dynamics 4 (D4) on the theme "The Lagrange principle":
D4 ACTIVITY 2: For the schemes shown in Figures 1-30, using the Lagrange principle, to determine the amount of force F (for the presence of friction - the maximal value) at which the mechanical system is in equilibrium. Inputs: G1 = the weight load of 20 kN, the torque M = 1 kN * m, drum radius R2 = 0.4 m (at a double drum also has r2 = 0.2 m), the angle a = 30 ° and coefficient of friction f = 0.5. Unnumbered blocks and rollers considered weightless. Friction on the axes of the drum and blocks neglected.
