Hi A few days ago while at a sea terminal at night i noticed a strange liquid floating on top of the water, it has a light brown color and when it floats undisturbed by any thing falling on it like for example Sand, Stones, or any thing else, it is just a Light Brown liquid, the strange thing...

Well let's assume that this is in a case where you have dirty old bolts and using a cheep torque wrench, in this case you'll use a torque angle gauge to be on the safe side. But if a good shining torque wrench where used with new fresh bolts, would it be necessary to use the angle gauge ?

There you go http://images.hemmings.com/wp-content/uploads//2013/08/torqueanglegauge_700.jpg P.S There is a few videos about this on YouTube, but I still don't get the idea of it

Hi Obviously the purpose of using a torque wrench is to tight a bolt to a specific tightens, but what i can't comprehend is the purpose of using a torque angle wheel ? Why are they used, is the torque wrench not enough ?

Term used in Engineering, but the picture is clear now thanks to you guys

So it's just a way to say that the pressure is below the reference pressure ?

isn't a vacuum and negative pressure the same thing ?.

Hi guys Is there any thing such as Negative Pressure, or is there only total vacuum 0 and nothing below that ?

Hi Why is there a voltage drop in a wire when there is a high current flowing ?. Is this due to the electrons colliding with the lattice which causes the kinetic energy that the electrons have gained trough the voltage to be transfer to heat energy ?
