The 11-N horizontal force acts on the handle of the socket wrench as shown. Determine the (a) moment of the 11-N force about point O and specify the coordinate direction angles a, ß and y of the moment axis. (8 points) (b) moment of the 11-N force about point B. (4 points) (d) magnitude of the moment of the 11-N force about the x-axis (1 point), (d) magnitude of the moment of the 11-N force about the y-axis (1 point) and (e) magnitude of the moment of the 11-N force about the z-axis (1 point) Use 85 mm, 280 mm, instead of 75 mm, 200 mm and 16° instead of 150. 200 mm 75 mm 20 N Mo = a = Me = Mx-axis = My-axis = Mz-axis =
