  • 18 Mechanical Properties Which Every Mechanical Engineer Should Know

    Selection of material is an important aspect for manufacturing industries . The quality of product is highly depends upon its material properties. These properties are used to distinguish materials from each other. For Example: A harder material is used to make tools.A ductile material is used to draw wires. So the knowledge of mechanical properties of material is desirable for any mechanical student or for any person belongs to mechanical industries. This post brings top 18 mechanical propertie

    Types of Welding

    Welding is a process of joining similar and dissimilar metals or other material by application of heat with or without application of pressure and addition of filler material. It is used as permanent fasteners. Welding is essential process of every manufacturing industries.  In fact, the future of any new metal may depend on how far it would lend itself to fabrication by welding. The weldability has been defined as the capacity of being welded into inseparable joints having specified pro

    Difference between Hot Working and Cold Working

    They both are the metal forming processes. When plastic deformation of metal is carried out at temperature above the recrystallization temperature the process, the process is known as hot working. If this deformation is done below the recrystallization temperature the process is known as cold working. There are many other differences between these processes which are described as below. Difference between Hot Working and Cold Working: S.No.

    CLASSIFICATION OF FLUIDS

    Ideal fluid: A fluid, which is incompressible and having no viscosity, is known as an ideal fluid. Ideal fluid is only an imaginary fluid as all the fluids, which exist, have some viscosity. Real fluid: A fluid, which possesses viscosity, is known as real fluid. All the fluids, in actual practice, are real fluids. Example : Water, Air etc. Newtonian fluid: A real fluid, in which shear stress in directly proportional to the rate of shear strain or velocity gradient,

  4. A fan coil unit is the name of the device which uses a coil and a fan to heat or cool a room without connecting to duct work. These devices are systems or machines that eliminates hot air and replace it with cold and humid air by circulating cooling the air. A Fan coil unit is a device that includes fan blower and coil for heat exchange. The task of this machine is to release air into the desired space. Cooling of cold water inside the coil (supplied through the chiller) and passing air from this cooling coil cause cool air. do you know something more?

  6. Hey there. I’m working on an electric skateboard project where I have a plank of wood with a bike wheal on the back and a chain to drive the whole thing. I can’t find the correct motor to power the whole thing and could really do with some help to do so. I need something with enough torque so it can move a lot of weight and it to be fast too. I can’t spend to much either. Thanks

    Linear actuator

    There are many ways that such a device can be made, and what Jek says may be the way this one works. It can also be done with a ball screw powered by a small electric motor. Without more details, no one will be able to say with certainty how t this one works. DrD

    Linear actuator

    If that's the air pressure gauge on a side, than it must have some sort of an air pump. If so, I'm guessing the capacity of this thing wouldn't be high. I mean it wouldn't be able to lift a car by itself. I'm guessing there is an air pump and some sort of an air bag (so that it could expand).
  14. Its Membranes cost is the reason behind its unpopularity. I think so.
  15. Hello This is S.Srinivas from wool industry. We have cupola furnace coke fired. We send Blast air thru Fan of capacity 11000 cfm and 50HP motor direct coupling. damper controlled We charge Raw material batch wise, 4 batches per hour and 500 kgs each batch. QUERY: When ever iam trying to open blast air damper more than 50%, it is taking 70 amps. So any suggestions to open damper to 90% without increasing the load by 65 amps.
  16. vibration is useful in many industrial applicable like material handing system, like screening..
  17. What is special precautions required for selecting fire rated rolling shutters? what is the basis and material used for designing fire rated rolling shutters? Up to how much time it can withstand fire without damage?
  18. Why multi stage OH1 or OH2 type pump are not used in refinery, chemical and petro-chemical, fertilizer ans Oil & Gas industries?
  19. it is force lubrication system, you may check API 614 for shaft lubrication system to study in depth..
  20. Stress and deflections are primarily function of diameter. Buckling could be said combination of both diameter and thickness. Stiffness (for vibration) primarily function of diameter. Mass (and material costs) primarily function of thickness.
  21. I’m doing a problem on minimizing mass of a hollow wind turbine tower. My design variables are the thickness of the wall and internal diameter. I’m having trouble finding constraint functions, since all that I could find (stresses, deflections, buckling) increase in value as both the design variables decrease, so if I pick two of them one will be “shadowed”/dominated by the other constraint. Does anyone have any creative ideas for another constraint, that preferably increases with wall thickness but decreases with internal diameter? Or maybe some other design variables combinations that relate to mass?
  22. Damien - You do bring up a great point. I would like to hear more about the approach you are taking in giving apprenticeships. Would you share?
  23. Also, adding more pulley means that the vertical movement reduced for each additional pulley. using 1 pulley, F = W, you move F 1 m, you get W lifted for 1 m. using 2 pulley, F = W/2, you move F 1 m, you get W lifted for only 0.5 m. using 3 pulley, F = W/3, you move F 1 m, you get W lifted for only 0.333 m. But mostly, what DrD said.... friction
  24. Do you want to make roller. With this tool you can make roller easily. This is tutorial video: https://www.youtube.com/watch?v=bQkY-0Pc7FA
  25. Not necessarily, some schools and colleges are sending students into the workplace with incorrectly achieved qualifications; I am not a cynic but a witness of this, this is why I left main stream teaching this year and pursued giving apprenticeships to budding engineers.
  26. Apprenticeships are an excellent way to go!
