Hmm.. in that case, the normal force would be shorter for both boxes than the force of gravity? Not understanding the part in brackets. It would equal the force of friction?
So, like this? Making sure that normal force equaled the force of gravity for both boxes, with the heavier box having a longer force of gravity than the lighter one. The force of friction would also be longer, I think.
Now I'm confused, you answered yes to the boxes having different and identical FBD. o_O
I was going to ask, would the heavier box (20kg) have a longer friction line than the 10kg box? I think the other two forces would stay the same length for both boxes (or maybe gravity would be a longer line...
Alright, thanks!
The question also says to draw a FBD for each of the boxes. Does the mass impact any of the forces or would the two have identical FBD?
Homework Statement
At a construction site, a small crane is raising two boxes of nails on a plank to the roof. One box has already been opened and is half full, while the other box is new. The boxes, including the nails, weigh 10kg and 20kg, respectively, and are both the same size.
If the...
