Question

The parallel forces F1 = 300 N and F2 = 60 N with the same direction are shown, while A1A2 = l = 100 cm. a) Find the value and point of application for the resultant force. b) Determine the arm d1, when it is known that d2 = 50 cm.

Answer 1

a)

$$300x=(100-x)60\\x=16.7\ cm$$

$$F=300+60=360\ N$$

b)

$$300x=(50)60\\x=10\ cm$$
