A rotating display platform is initially stationary and is free to turn about its central pivot. The forces on the platform produce a total clockwise moment of 15 N m and a total anticlockwise moment of 11 N m.
Which statement must be correct?
The platform starts to turn clockwise because the clockwise forces must be larger.
The platform starts to turn anticlockwise because the resultant moment opposes the larger moment.
The platform remains stationary because both clockwise and anticlockwise moments act.
The platform starts to turn clockwise because the clockwise moment is larger.
