i need help with this problem please help
(If you use a horizontal force of 30.0 N to slide a 12.0kg wooden crate across a floor at a constant velocity, what is the coefficient of kinetic friction between the crate and the floor?)
PLZ HELP AHHHHH ITS DUE TMRW SO PLZ HELP
More advanced FBD problems--need some tips!
Okay, just got assigned 3 more FBD-based problems with which I not only have to do the normal calculations, but also use various computer programs of choice for additional calculations, plots, etc.
As such, these are a bit more advanced than the FBD...
Okay, started these problems with just the FBD drawing parts, but need some more clues as to how to go about starting them, i.e., just what equations/order is used to set them up, etc.:
1) Supposed to write the 6 equations of equilibrim, so, for example, is this what I need to do...
Hey, i need some insight for free body diagrams.
Say your in an elevator and your nomral wieght is 500N and there also is a scale.
The scale starts to read 450N. Which means it would be accelrating downwards. So for the FBD, 500N would be in the middle. Then would there be an arrow pointing...
In the following situation, how should I draw a FBD and what forces should I include? A metal rod has a string coming out of one end. The other end of the string is attached to a small mass. The metal rod undergoes spinning action by the hand so that the string with the mass attached spins...
I got alittle confused on something...
say an elevator is moving downward and its speed decreases.
If you are drawing a FBD of a block inside the elevator,
there are only two forces acting on the block, normal force from the elevator floor and weight force. But since elevator is decreasing...
I can't figure out this problem
Lets take triangle ABC
A
B C
a median (D) goes from A to the midpoint of BC
a median (E) goes from B to the midpoint of AC
Prove that triangle AEF = triangle FBD
Since a median divides up a triangle you know that
triangle ABD = triangle...
