2. (1 point) (Numerical Full-in)Two connected masses (massless pulley) - assume frictionless surface, no air-resistance, andmassless pulley.8.00 kg6.00 kgWrite down the Lagrangian (L) for this system (before the 8-kg mass falls off the table) andobtain the Euler-Lagrange equation. (Note: Compare it with Newton's Second Law.) Set y=0 atthe pulley and let positive y-axis pointing down - be careful about your expression for thepotential energy. g=9.8 m/s². Compare it with Newton's Second Law.(a) L

SOLVED:Continuous cable A D B runs over a small frictionless pulley at D to support beam O A B C that is part of an entrance canopy for a building (see figure). Assume that the canopy segment has a weight W=1700 lb (a) Find the required cross-sectional area of cable A D B if the allowable stress is 18 ksi. (b) Determine the required diameter of the pins at O A, B, and D if the allowable stress in shear is 12 ksi.
