Hi The materials is AMS 5629 (13/8 PH VAR). Thanks

Hi The materials is Hardening Stainless Steel bar, all my units are in N and mm, just one thing else I don't know how to use the number of landings in my calculations as I don't have any other information about it. Thanks

Hi Thanks for your reply, I have attached the dimensions of the landing gear which you asked for. Thanks

Hello I have an assignemt to analysis a landing gear for the cyclone earoplane, an initial design being supplied, I have being askedto check for the suitability of the part, the conditions are: Aircraft mass with fuel: 43000 lbs Landing speed: 65 Knots Maximum deceleration: 3g Each part...

Hello I have an object of mass=3.915 kg falling down by (300 mm), how can I find the force?

Hello Can anyone help me please, I want to write a batch file in MS-DOS to: Communicate with the serial port, send data to the serial port from a specified file and for a respond to come back from the driver that first command being done and now ready for next line of data to be send it...

Hi Thanks for your reply Iam using a different power supply for the stepper motor and the stepper motor unipolar?

What's the difference between Isotropic and Homogeneous material? Thanks for your help

Thank you very much for your help Really the stepper driver will not be controlled by the serial port it just take in waveforms to control the firing of the coils? for the software I will run Windows XP and I need to writ a programme in MS-DOS after I run (cmd), the programme should send a...

Hi and thanks for your help I have a table in Excel spreadsheet which is containing data to motor through a stepper driver I can convert this spreadshhet by save as CSV file, the problem I have know is to write a programme in MS DOS throgh windows to send this CSV file to the serial port and...

Hi Can you please help me here? I want to know: 1- the difference between nodal stresses and elemental stresses. 2-How the computer uses these stresses if it is to use strain energy as the convergence criteria? 3-How the sub-structuring technique can be used to model large structures...

Hi I want to know what's the difference between the H and P method solutions for static analysis problems, if you can explain it to me? Thanks for your help

Hello I have a question if anyone know the answer I appreiatete it, the question is that when doing FEM for a frame in just 4 elements is more correct to solve it by using stiffness matrix and spread sheets or by using ProE is more correct answer can be found, please can you explain it for me...

Hello Thanks for you help, I have to design a gearbox which will be connected to an electrical motor with a 11 Kw, 960 rpm, 42 mm shaft diameter, I want the gearbox to rotate a sprocket with a diameter of 337 mm in a speed of 40 rpm, I don't know how the gearbox is to be designed for the...

Thanks I want to solve the problem by using FEA, but I don't know what's the stiffness matrix for this problem? I don't have a clear information about this kind of situation. Thanks for your reply
