Sir, I do appreciate you for taking time to solve my problem. I would be glad if you could please take a minute to consider the following, I have a few constraints here for motor, Maximum Voltage = 48v Maximum Power = 400W I have designed by tricycle and it has mass of 400kg (including...

Thanks a lot Sir..! I have been on these friction, coefficients and all for quite a lot of time and now finally figured out... Once again... thanks a lot for helping me out. Aby Joseph

I completely understood your method of calculating Force(from Mass and Acceleration) and Torque(from Force and Radius) Please be patient with me but http://www.researchgate.net/post/How_can_we_calculate_the_required_torque_to_move_a_massive_object_by_means_of_gear_assembly2 too advocaties...

Thanks a lot for the prompt reply... I got the equation from https://www.physicsforums.com/showthread.php?t=528133 It tells: The COF of rubber vs pavement which is (.75 N) F= MA F= (136.08 kg)(9.8 N/kg) = 1333.58 N F(normal) = 1333.58/2 = 666.8 N F (friction) = (.75)(666.8N) F=...

I am having a real tough time determining the torque required to power an electric motor used to drive a cycle. I have calculated the Torque as: Torque = μ X mg X r(radius of the wheel) Now I am confused as what is μ. I know it's the coefficient of friction but, not sure whether I have...
