Assume constant velocity. There is no acceleration and friction on the ramp.
The force needed to push up the incline is mgsinθ which is smaller than directly raising up , i.e., mg. This is mechanical advantage of the incline.
But how about the reaction force component mgcosθ if I hold...
Thanks!
I know the work done is path independent.
But how about the mgcosθ ( the reaction force) if I carry it (in my hands / put it on my head)
If I carry the mass in my hands, the reaction force exerted by the incline is ( my mass +m)cosθ.
The reaction force I need to keep the mass from...
Assume there is no friction.
When I push up a mass up the inclined plane ,the reaction force (mgcosθ) is offered by the plane. The force I need to apply is Mgsinθ, <mg.
If I carry the mass, (e.g. I put it above my head) the reaction force is provided by me.
The total force I need to provide...
Is there any difference in the force I need to apply between pushing and carrying a mass upward along an inclined plane with a constant velocity ?
I'm puzzled with the normal force of the mass at the inclined plane. When I push up a mas, the normal force of it is exerted by the inclined...
