If I have a 120V - single phase motor, is current simply equal to power/voltage?

I have been looking into switching from 304L to a cheaper alternative. I noticed in MetalMickey's thread, that it was suggested to switch to SS201, SS439, or SS430Ti. What type of applications would these materials work for? I am looking to use it on a conveyor used to move ash. The...

I am just learning femlab, and to do simple problems it's coming along well. but i was wondering if anyone knows a good website that has a list defining error messages? Or does anyone know if it is in one of the manuals? I have searched through them but haven't found anything. I am wondering...

Can anyone tell me what the error message "Solnum out of range -- Maximum value: 0" means, and how to correct this error?

I don't know if anyone can answer this question. But I was just curious if engine braking a car (manual transmission) has any negative effect on the motor, or gearbox?

Can anyone tell me what physical factors play a role in abrasion resistance? I would think that hardness would play the most significant role, but is it the only deciding factor? I guess, maybe a low thermal conductivity to keep the material from heating up, and softening. Although, I don't...

Does anyone know how to calculate the thrust force acting on a bearing used for a screw conveyor?

I am trying to spec some pitot tubes for an application where air is moving through a duct. My data values are as follows: velocity of air = 14.1 m/s static pressure (SP) = 4.5 in water is the medium in the tube I'm trying to find the differential pressure (DP), and i am not a mechanical...

I am looking to find the nomenclature behind astm stainless steels. I've noticed that often times the name is followed by something such as 'CB 30', or 'CF 10'. Can anyone tell me what this extension to the name is? And preferably a webpage or book that has the nomenclature so I can figured...

I have seen a few forums related to this topic, but I always seem to get ridiculously small HP numbers. If i have a conveyor 4"OD, 8'LG., i get an approx. volume of 0.7 cuft. I have a material density of 45lb/cuft. Torque = (0.7 * 45 ) * 2" (moment arm) Torque = 5.2 lb-ft my conveyor...

I am looking to develop a new grate for a combustion chamber in a cost cutting measure. The grates themselves can get up to 900 degrees C. We have been using SS, but they are really expensive, not hard enough, oxidize easily, and cause us to have to shutdown the whole system to replace. I...
