hi,
can anyone advise me what is the proper way in computing the friction between wheel and the axle? its just a simple door carrier(please refer to the drawings above).
thanks
hi tim, hi molydood,
please correct me if I am wrong.
here's my computation:
Weight of door=100 kg
Number of wheels= 2
Weight per wheel =(100kg)/(2)= 50kg
F1= αW / r
F1- resistant force of a single wheel
α - coefficient of rolling friction
W - weight
r - radius (0.015m)...
what is the required force to start moving a sliding door weighing 100 kg with two rollers.
what are the forces acting on the system?
shall i used rolling friction on this?
what formula to use?
thanks a lot.
