Question

You are working on a project to make a more efficient engine. Your team is investigating the possibility of making electrically controlled valves that open and close the intake and exhaust openings for an internal combustion engine. This device is mounted on an axis so that it can spin freely to close the valve. Your assignment is to determine the stability of the valve by calculating the force on each of its sides and the net force on the valve. (Another team-member is calculating the torques on the device and needs your results to do this.) You may neglect any forces other than magnetic forces. For example, neglect forces due to the intake/exhaust when the device is in operation.

Answer 1

net force (F) = F-F2 = 4665703 - 2.332x103 *solution is PAGE Considering the figue , conditions with polemeters from the question.
