a 20Ib force is applied to the control rod AB as shown. Knowing that the length of the rod is 9in and a=25 degrees determine the moment of force about point B by resolving the force into horizontal and vertical components
ME2120-1 HW2 Due 9.30am Tue Sep. 18 (For this set of homework it is not required to draw a separate free-body diagram. But it will be helpful if you sketch the force on the figures given with the problems) Hint for part (b): The smallest force Q must be perpendicular to OB.
