E E W X R A door handle is acted on by a vertical force, F, at point B and a couple, E, about the point O. The force and couple can be replaced by a single, equivalent force, R, applied on the door handle. Variable F E Value 500 250 Units [N] [N] 300 [mm] Given the information in the table above, determine: 1) the sum of moments by the force and couple, [N-m), (3 sigtig) CW B F W 100 [mm] 40 [mm] Your answer is incorrect. Marks for this submission: 0.00/18.00. This submission attracted a penalty of 6.00. Total penalties so far: 12.00. 2) the distance along the lever from O that the equivalent force acts at, [mm], (3 sigfig)
