Two forces each of 5 N act vertically upwards and downwards respectivly on two ends of a uniform metre rule which is placed at its mid-point as shown in the diagram.determine the magnitude of the resultant moment of these forces about the midpoint. |
|
Answer» The two forces each of 5 N form a couple ∴ Moment of the couple = Either force x perpendicular distance between the two forces = 5 x 1 = 5 Nm (anti-clockwise) |
