I have (what is seems to me) and easy statics problem to solve. I simply need to work out the tension in a single continuous wire connected to the load (with eccentric COG) on two ends - as shown, and passing through a frictionless pulley on top. I know that the tension in the wire must be the...

Thanks very much. That's what I thought I was missing, but I wasn't sure. Regards

Hi everybody. I need to calculate the energy required to melt 1mm^3 of carbon steel which is initially at 20 degrees C. Knowing the melting temp (1535 C) and the specific heat per unit volume (C_v), can I calculate my energy (Q) as follows?: Q=C_v*(1535-23) = my answer Or is it wrong...

So, will hydrogen flame cast a shadow? And ok, hydrogen flame may be practically invisible, but I suppose it changes the gaseous structure of the air - meaning gases in hydrogen flame (their amounts and behavior) are different than gases in the air at room temperature. Even though it may look...

You're right. I did not clearly classify fire and this makes the whole thing a more complex. I guess it is necessary to make a distinction among different kinds of substances (our fuel) that undergo combustion reaction that causes visible flame to occur. Let's take it to another level. Is...

Hi. So my friend thinks he's smart, and one time, while we were talking, he asked me whether fire can produce shadow. Of course he does not know the answer, but knowing him, he asked me this question to show that I am not smarter than him. Nevertheless, his question started bothering me, because...
