answer & explanation:
"the force on a cutting tool are 2600n vertically downward" sounds a little unusual, since most of the time, the tool is above the object to be cut in such a way that the force acting "on the tool" is upwards. we will accept the statement as it is (downwards).
since the two forces are acting at right angles to each other, the resultant can be found using pythagoras theorem, namely
resultant = sqrt(2600^2+2100^2) = 3342 n (approx.)
the angle can be found using the arctangent function, or
angle = arctangent(2600/2100) = 51.07 degrees below the horizontal, since the 2600 n force is acting downwards.
on/off components of a pid controlled accumulates the error over time and responds to system error after the error has been accumulated.
the drive force for diffusion is 7 fick's first law can be used to solve the non-steady state diffusion.
you ruin your mop that way. it will clump up and than you'll have a mud mess.
