The discussion revolves around understanding the direction of the resultant force acting on a blade in a fluid dynamics context. Participants are questioning why the resultant force is directed downwards towards point A, despite the presence of horizontal and vertical force components that suggest an upward resultant force.
The discussion is ongoing, with participants providing insights into the calculations and questioning the assumptions made regarding the forces acting on the blade. There is a focus on clarifying the relationship between the forces on the blade and the forces exerted by the stream of water, though no consensus has been reached on the direction of the resultant force.
Participants are working with specific force values and components, and there are indications of potential typos in the equations being referenced. The discussion includes the need to negate certain forces to determine the forces acting on the blade, which adds complexity to the analysis.
The calculated Fx and Fy are forces on the stream of water. To get the forces on the blade you have to negate both, giving 2.12kN to the right and 0.735kN down.werson tan said:
isnt that the the resultant force on blade and forecs of steam of water are of same magnitude and same directionharuspex said:
Action and reaction are equal and opposite. The force the blade exerts on the stream of water is equal and opposite to the force the water exerts on the blade.werson tan said:
