These three cartoon creatures are trying to pull a statue. Graphically find the resultant vector if:

The Ant applies 100N@2200

The Penguin 200N@2400

Jackie Chan 300N@3080

Which vector is which?

Will it move, and which way

will it go ?

0

90

180

270

For graphical vector addition to work, the arrows must be drawn at exactly the right angle using a protractor and must be drawn to scale (proportionally) using a ruler. Check this drawing with a ruler and protractor

The Ant applies 100N@220

The Penguin 200N@240

Jackie Chan 300N@308

200N

300N

100N

R=240N@2700

Combining the vectors “tip to tail”, regardless of the order, gives us the resultant.

How can we graphically find how big this resultant is?
