So that means:
Fsubf = 24.5
24.5 = mu x W x cosTheta
24.5/(mu x cosTheta) = W
Thank you so much, I did not recall that relationship between the Friction force and muN.
I have :(. I don't know the weight, only what I gave above. It seems to me like I need one more piece of information, such as the weight. That is why I posted here, to see if I was missing something obvious.
I can't figure out how to get the mass of this object, with the information given:
Inclined plane with angle relative to the ground of 20 degrees.
It takes 70 Newtons to get the object moving up the plane.
"Mu" of static friction: 0.35
All my example problems involve an object going...
