Question
Find the resultant of the force system as shown in the given figure.
Solution
Taking forces having direction upwards as positive. Net force = 200+300-200-300
=0 N
Taking moments of the forces about the point A Taking anticlockwise moment direction as positive
∴ MA = 200 x7 +300 x 5 – 300 x2
=2300 Nm (anticlockwise direction)
The resultant force is 0.
Net moment is 2300 Nm(anticlockwise)
