F = 200 N F:-100 N F = 400N 1300 5 = 500 N (a) (b)
In each case, create the parallelogram law to show that Fr = F1 + F2, then lestablish the triangle rule, where Fr = F1 + F2. Write down the known and unknown sides and internal angles
F = 200 N F:-100 N F = 400N 1300 5 = 500 N (a) (b) In each case, create the parallelogram law to show that Fr = F1 + F
