Problem 1: The The uniform 30-kg ventilation door OAP is opened by the mechanism shown. Plot the required force in the cylinder DE as a function of the door opening angle over the range 0 < 0 < ®max, where 0max is the maximum opening. Determine the minimum and maximum values of this force and the angles at which these extremes occur. Note that the cylinder is not horizontal when 0 = 0.
