Baluncore's latest activity
-
Baluncore replied to the thread Electromagnet magnetic field issue.You should try soft iron or mild steel for the pin, not stainless or high tensile steel. The more the pin material costs, the worse it... -
Baluncore replied to the thread Electromagnet magnetic field issue.Yes, check the current tomorrow. Maybe the 12 V supply has insufficient voltage under load. Is the pin made from iron, steel, or maybe...
-
Baluncore replied to the thread Electromagnet magnetic field issue.Is it using an AC or DC supply ? Is the wire the same gauge or diameter ? Can you measure the coil current ?
-
Baluncore replied to the thread Automotive Motor for slider crank.There are too many possibilities. Almost any small electric motor will do the job. How you construct the slider crank, and mount the...
-
Baluncore replied to the thread B Could we ever create a black hole?.So you want a handy 1 kg black hole to pass around the classroom ? It will be smaller than a normal proton, how will you hold it ? How...

Baluncore replied to the thread I The Physics of unloading sand from a barge.Vibration is used to remove air bubbles from concrete, and would separate excess water from more dense sand, thickening the fluid. The...

Baluncore replied to the thread I The Physics of unloading sand from a barge.You start with the pump input pipe resting at a low point on the surface.
-
Baluncore replied to the thread I The Physics of unloading sand from a barge.The sand in the barge was initially saturated. The pump inlet was placed on top of the load at the start, then the hoses were used to...

Baluncore replied to the thread B Why can't Solar panels be hemispherical, or a curved strip type?.On pitched roofs, we have a constraint that requires the panels not protrude significantly beyond the existing roof profile. That...

Baluncore replied to the thread I Off resonance driving of a MW/RF cavity.At 100 MHz, the 10 GHz cavity would be well below the cut-off frequency. Depending on the cavity coupling technique, it would appear as...
-
Baluncore replied to the thread Which is which among Cyclone, Hurricane, and Typhoon?.Are you saying that tornadoes are spawned, attracted, and strengthened by the warning sirens, in the same way that fog horns thicken the...
-
Baluncore replied to the thread Automotive Motor for slider crank.How fast must it turn? What force is required? What work will the slider crank do?
-
Baluncore replied to the thread 3-terminal device external modeling.For a circuit to be without stored energy, it must be a matrix of resistors. For such a three terminal device, you would be unable to...
-
Baluncore replied to the thread 3-terminal device external modeling.The characteristic curve does not show resonances, nor charge or information storage. The S21 parameter is the forward transfer...

Baluncore replied to the thread 3-terminal device external modeling.Only if it is linear, and you have the four scattering parameters at a number of different frequencies.
