Q.3) The structure below is subjected to a set of forces as shown. a. Replace the given system by an equivalent resultant force and couple moment acting at point 0. Draw the equivalent system. Reduce the equivalent system from part (a) into a simplest resultant (single force) and nd the x- and y- intercepts for its line of action. Draw the simplest resultant and include a dashed line showing its line of action. F2 = 220 lb F3 = 150 lb a, = 125 lb
