In the given diagram, the portion of a bridge truss is subject to four loads indicated by the arrows. For the loading shown, determine the (a) ( 2 pts ) resultant

of applied four forces. (b) (

corresponding moments about point

and the resultant moment

. (c)

location in the

plane through which the resultant passes. Note that the point of application of 120 kN force is at height 4.5 m from the

plane, and consider the structure as weightless.
