How do manufacturers size torque converters for a particular vehicle? Do they do a trial and error until they get the characteristics they are looking for or are torque converters given classifications that can be used to size them for a particular vehicle weight, torque, etc? I'm trying to size...
I have an application where I need to power a small automotive relay for 15-30 seconds after cutting off electrical power(12 volts). I thought there was a 555 circuit that could perform this function but cannot find it. If someone knows the name or can provide a link to the circuit that I am...
I'm in the planning stages of starting a consulting business to provide companies with technical guidance on improving their processes. I plan to create a report with recommendations on how to improve their business and then sell machine design and project engineering services to them based on...
I put together a stand alone oil system to feed a turbocharger and am having problems with the pump drawing too many amps(10A).
The system goes like this:
Turbo Outlet ->(3/8" Line)-> 1 Gallon Vented Oil Tank ->(3/8" Line)-> Pump Inlet ->(5/8" Line)-> Pump Outlet to Tee Fitting ->(5/8"...
I've been trying to make a drive by wire throttle body work with a different model controller and am having an issue with developing a circuit as a work around. Please forgive me if I am way off base here as I am a mech. eng. and have very little electrical experience.
From what I gather when...
I'm piecing together a junk yard 5.3 engine from a 2002 Suburban that has drive by wire throttle. When I found the engine the throttle body was missing so I figured I could easily find a replacement off another vehicle. What I found out is that from 2002 to 2003 the throttle body design was...
How do automotive manufactures measure a newly developed vehicles uni-body type structure for performance in various driving conditions? I'm looking for some guidance on how the test equipment is setup and what type is used.
Thanks
I've been noticing a lot of engineering jobs posted in my area and some family from another part of the country also commented on the same thing. Are we on the verge of another era where engineers are going to be so high in demand that college graduates will show up to interviews in shorts and...
Why did you decide to become an engineer and what was the biggest misconception that you had about what an engineer does before working in the profession?
For me I started taking automechanics at community college and realized quickly that I didn't need to pay someone to teach me how to repair...
I plan on making up some business cards to assist me in job hunting and networking. Should I call myself a "Mechanical Engineer" on the card? I have a BSME but have not taken the FE/PE exams. What is another title that would tell people what I have to offer without breaking any laws or offending...
What are some industries that most people consider crappy because of the travel, lifestyle, working hours, etc. but make a good career if you can adjust to them? I've already been interviewing with the major railroads but need more ideas in case I don't get hired by any of them. I'm interested...
I'm a mechanical engineer but I am currently serving in the U.S. Army. After we come in from a field training exercise our machine guns have a lot of carbon build-up. To help accelerate the process of recovering our weapons I would like to use a hand held wire disc to remove the carbon. The...
Hopefully someone can help me. My company is interested in converting a Windows based CNC Router into an industrial printer. We have some textiles that we are stenciling information onto and would like to use the CNC to do the printing for us. Here is the idea, buy an industrial inkjet printhead...
We have a Thermwood router that we would like to modify to print on the blankets that we manufacture. Does anyone have any experience with an application like this. Is there a machine already available that you can put a generic part and specify where to print?
Thanks
Some companies seem to employ a lot of engineering coops. Do companies get some type of credit or tax deduction for having coops? What are other reasons why some companies have a lot of them?
This should be an easy one for the welding experts on here. We have a brass plug that is to be pressed into a brass body that we would like to laser weld(no filler). For the allowable shear stress in this situation I am assuming a value of 8,700 psi[(0.3)*29,000 psi(29k from machinery handbook...
Hi,
I am interested in making a minor modification to my truck to help obtain better gas mileage. I can either put my tail gate down or I can buy a bed cover. Which would help me achieve more savings in gas mileage? I know the initial investment of a bed cover is going to probably overshadow any...
We have a zinc plated part that is exposed to refrigerant. Corrosion has caused the zinc plating to come off and ruin the part. Does anyone have any idea what could have caused this rapid corrosion.
