It does not make much sense to dig into structural details before the very basic mechanics is examined - The weight of hopper and material inside the hopper is shared between the hinge and the load cell. If you can make sure the distribution of wieght between the hinge and load cell is even all...
Suppose you cannot compare the sound energy and pressure energy in the four mechanicl boxes at all.
In case of the pressure energy of air pumped by fan, if there is a peak of pressrue from the fan, the air inside the box absorbes the addtiional energy by increasing the pressure which is to be...
If you look at performance curve of a fan you see that delivery volume decreases as back pressure increases. Specification of flow say 400 gpm or 600 gpm corresponds to just one point on the curve, which means the spec throughput is defined just under one particular pressure.
The actual back...
I want magnetic force on one end of the magnetic bar only, but not on the other end. Will it work if I attach a big piece of iron on that end of magnetic bar which I do not want to have magnetic force? Imagine that big piece of iron will absorb all the magnetic flux from that end which i want...
