    What Is the Coefficient of Friction in an Equilibrium System?

    the weight of the y component acts down on him and the y component of T acts upwards so ∑ Y forces = 588.6N - 49.05N = 539.55 normal force will be equal in magnitude t the y foces μ = 84.95 N / 539.55N = 0.1574 HAVE I UNDERSTOOD IT CORRECT LY??

    What Is the Coefficient of Friction in an Equilibrium System?

    Solution for friction equilibrium THANKS FOR GUIDING ME - I NEED FURTHER HELP I have solved this according to your advice. Confusion i have about angle. i did 90-60=30 x Component of T = 98.1* COS 30° = 84.95N y component of T = 98.1 SIN 30° = 49.05 SUM X forces is only 84.95N...
