Pulley with Friction | 3 Blocks | Newton's 2nd Law | Dynamics

Welcome to Engineering Hack! In today's video we have yet another pulley problem. It is a step up from problem 12.14 (   • Pulley with Friction | 2 Blocks | New...  ), that we solved previously, so make sure to check it out before diving into this one. Again, we are not only interested in the motion, but also in the forces that cause the motion to start with. We'll be applying Newton's second law to be able to arrive at conclusions in regard to the whole system and then again to be able to calculate the forces and accelerations for the individual components. We are using free body diagrams to isolate these components and evaluate them as individual control volumes. This is problem 12.30. Problem statement: The coefficients of friction between blocks A and C and the horizontal surfaces are μs =0.24 and μk=0.20. Knowing that mA = 5kg, mB = 10kg and mC = 10kg, determine (a) the tension in the cord (b) the acceleration of each block. Answer: T = 33.63N Acc of a = 4.764 m/s² rightwards Acc of b = 3.083 m/s² downwards Acc of c = 1.402 m/s² leftwards To learn more please watch the video till end and if you have a question just ask in the comments section.
