To check the reactions by calculations take moments about the line through B1: clockwise moments = anticlockwise moments . W 1 x 1 + W 2 x 2 + W 3 x 3 = B 2 L .
How do you find anticlockwise moments?
- Anticlockwise moment. The anticlockwise moment is the child's moment = Fd. Perpendicular distance of child from the pivot = 2.4 m. ...
- Clockwise moment. The clockwise moment is the parent's moment = Fd. Perpendicular distance of adult from the pivot = 0.8 m. ...
- Total clockwise moment = Total anticlockwise moment. 0.8 F = 600.
What is the sign of anticlockwise moment?
Conventionally, an anticlockwise moment (one which tries to rotate the body in an anticlockwise sense about the axis of rotation) is considered to be a positive moment and the magnitude of the torque on the body is written along with a positive sign.
