Two workers act with a force F = 250N on the handles. The diameter of the drum is D = 315 mm, the arm of the lever is 350 mm, the number of teeth of the gears is: z1 = 16, z2 = 80, z3 = 14, z4 = 112. It is necessary to calculate how much traction force can be achieved.
Your diagram needs more explanation. It is not clear how the forces are transmitted from the left crank to the drum. Are the two cranks connected to the same shaft? What is item 2? What does the sawtooth line across Z3 mean? Lastly, find out when your professor has office hours and stop by for some one on one mentoring.
