That equation doen not seem accurate
You put the weight down..not the force pushing down Te acutal force on the casters is as follows 181 pounds = 82.1 Kilograms so 82.1*9.8m/s^2 = 804.58 Newtons of force total Now... to find the coefficient of friction... Friction = Mu*Mass*Gravity or in this case ----> Mu(804.58) so in order to move this goal... You plug in the following Force of Robots Push or Pull - MU(804.58) = 82.1* Acceleration Now...to fin dthe minmum force needed to move the goal... You set acceleration to zero... So you get... Force of Robots Push or Pull - Mu(804.68) = 0 Force of Ropbots Push or Pull = Mu(804.68) Force of Robots Push or Pull / 804.68 = MU There you go...just plug in the force from your robot and you should find mu. I need to check some notes..but there might be a better way... And remember Its in Metric G.Goldman |
