its 1100 actually :-s

the sheaves we're using are small and have very small groves as are used in case of airborne chair lift systems

great idea.. this idea worked great for us... both the ends were untwisted and inserted into each other over a span of about half meter.. then applied pressure and a little brazing. the joint is now perfect although a little more in dia but okay!

the rope is 100 meters long. and the traction system is such that we can't install a rope in it which has no termination. so there had to be a joint which can carry equal tension and pass over those sheaves as well. the good thing is that the joint will not pass through end sheaves as in...

hello friends, i am currently working on a project in which a steel rope is used to carry an object in a loop just like a chair lift. what i want to ask is what method can i adopt to make a joint of the rope that can pass through or over the pulleys and not de-track too. The rope diameter is 8...

but i the question is that how much torque do i have to apply..

how about incorporating the bearing friction to maintain the desired angular velocity?

Calculating Torque?? i wonder how would i calculate the amount of torque required to give a rectangular piece of marble, an angular velocity of pi radians/second given the angular moment of inertia of that slab. The bearing supports holds a coefficient of friction of 0.2 and the shaft...

you can use Euler's theory for finding those stresses

well, what you want is not impossible, but you would need to involve some mathematics in your solution :-P i could've worked with a general solution about the variation in the thermal resistance with temperature and pressure of an ideal gas but I'm stucked in a job deeply . . Regards

I wonder if there is a mathematical formula to calculate the flow rate of a fan if following parameter are known Fan effective diameters Blade Angle ( Pitch ) Number of Blades Speed ( RPM ) Power Consumption Pressure at inlet of the fan Regards

yeah i will measure the pressure at inlet and outlet of the fan and then the difference of these will give me the required value.

yeah that's right. but according to mender, if you get a greater rise in the water height for the same pressure differential, that will increase your measurement resolution; this is what i am agree with. the formula for calculation of the pressure is P = density*height*g where g =...

thanks mender for explanation. i got your point that when the liquid column is inclined. it will be more sensitive to the pressure response. . . THANKS1

of course repeated compression and expansion exerts a fatigue stress in the pressure vessel. within elastic limit, the vessel would face as many stress changes as there are strokes of compression expansion
