Find the resultant for the force systems in Figure 1.16.Find the magnitude, line of action, and sense of the resultant.

Take two values, say 1 and 2 and use the relationship, (picture)\  Are the values in both sides of the equation the same? What is the difference? Talk about this.

A spelunker is surveying a cave. She follows a passage 160 m straight west, then 230 m in a direction 45 degree east of south, and then 280 mm at 30 degree east of north. After a fourth unmeasured displacement, she finds herself back where she started. Part a)Use a scale drawing to determine the magnitude of the fourth displacement. Express your answer using two significant figures. Part B)Determine the direction of the fourth displacement. Express your answer using two significant figures
