The discussion revolves around calculating the power required to pull a body of mass m up a smooth incline at a constant speed Vo. The problem involves understanding the forces acting on the body and the relationship between work, force, and power in the context of inclined planes.
The discussion is active, with participants providing insights into the calculations and questioning assumptions about the forces involved. Some guidance has been offered regarding the components of forces acting along the incline, and there is a focus on deriving expressions for power in terms of angle and speed.
Participants note the importance of considering the angle of the incline and the constant speed condition, as well as the implications of these factors on the forces and power calculations. There is a recognition that the net force must be zero when the object moves at constant velocity.
mg is the force, not the work done.imy786 said:Power= mg/ time
Right. [itex]P = mg \sin (a) v_0[/itex].imy786 said:power= vsine mg
