A circular theatre platform can rotate about a vertical axis through its centre. Two stage workers apply horizontal forces to the platform at the same time. The forces produce moments in opposite directions.
| Worker | Force in N | Perpendicular distance from the axis to the line of action of the force in m | Direction of moment |
|---|---|---|---|
| 1 | 48 | 1.25 | clockwise |
| 2 | 35 | 0.80 | anticlockwise |
Calculate the resultant moment about the axis and give its direction.
