The discussion revolves around determining the torque vector and its quantity based on a provided sketch. The subject area includes concepts of torque, force application, and rotational mechanics.
Participants are exploring the implications of force application on torque direction and magnitude. Some guidance has been offered regarding the irrelevance of the path taken by the force application in determining torque direction.
There is an emphasis on understanding the relationship between the force's point of application and the resulting torque about the axle. The original poster's calculations and assumptions are being scrutinized for clarity.
The weight acts at the mass centre of the mass, so you would draw the force vector straight down from there. This is important for determining the torque it has about the axle, but for the purpose of figuring out the linear force at the axle the line of action does not matter, only the direction.Pinon1977 said:
Yes. The path the rigid member takes from axle to point of application of force is irrelevant. You could make the member an entire disc centred on the axle.Pinon1977 said:
