Part A
Determine the resultant force.
Express the \( x, y \) and \( z \) components of the resultant force in newtons to three significant figures separated by commas.
Part B
Determine the couple moment acting at point \( O \).
Express the \( x, y \) and \( z \) components of the couple moment in newtonmeters to three significant figures separated by commas.
