I have been pretty much lost on the following questions;3.1 A 30lb force is applied to the control rod AB as shown. Knowing that the length of the rod is 8 in. and that a=30 degrees, determine the moment of the force about B by resolving the force(a) into horizontal and vertical components, (b) into components along AB and in a direction perpendicular to AB.
