Problem $7$:

Consider the pipe structure projecting from the wall at point $"A".$

Find the resultant force and couple moment acting at point $"$A$".$ Express the

resultant force and couple moment in Cartesian $($vector$)$ form. $($Hint: the $1,000$ lb

force needs to be expressed as a vector and the "dimension box" provides the

information necessary to define the unit vector in the direction of $F.$ This is a $3-$D

version of what you have been doing for $2-$D problems. Check the Position and

Force Vectors review at the end of Chapter $2.)$
