Hi all,
I have attached a 2 page spec sheet on a an LCD display component that I am trying to get to work. I am conforming to its 3V operating voltage by supplying it 3V to the pins. The display only flickers for a second and sometimes not at all. The component itself works and have cross...
Hi all, I'm not an electrical engineer but a question is itching my brain.
How does one convert three phase power to single phase power? (preferably with a diagram attached?)
The reason I ask is that the three phase power transmission system is the de facto power transmission system.
Also...
Hi all,
Any chance anyone has received quotations or deals with investment casting products?
I can only receive limited quotes in my area and want to benchmark against widely accepted costs worldwide for interest.
On a high level, the part I wish to cast is a single stage model jet engine...
Can someone please correct me on my interpretation and explanation of polytropic efficiency, because Saravanamuttoo et al explanations are pretty atrocious. I see it as (applied to compressors, axial, that is):
NB Assumption: Every individual stage of an axial flow compressor has the same...
Hi all.
On the following link:
http://lightbucket.wordpress.com/2008/02/24/insolation-and-a-solar-panels-true-power-output/
scrolling down a little bit from the top, gives a table of average daily 24hr insolation. Due to it being a 24hr average, to calculate the energy /m2 over a total day we...

Old one got locked. Its that time again and I got a couple issues.
Can anyone validate my last post showing step by step design process? Is that what you would follow when doing designing suspension?
I also cannot for the life of me see what is compromised when the RC is...
Hello all
I have studied mechanical engineering and have now just over one years experience. My current job is shocking. I mean really shocking. I have wasted time not doing much and been used as a technician (!). I am fed up and am about to resign. Please note, this is not a spur of the...
Theory tells us that under a compressive load, a circular, hollow, cross section is the most efficient in carrying the load. This is because a circular cross section does not have in it a "least moment of inertia". i.e. there is no "weak point" to flex about like a flat ruler for example.
Can we...
After reading a brief description on fasteners, their nature of loosening etc etc, its incredible the volume of science behind the simple bolt and nut. I have a few questions regarding this.
On the topic of bolt/nut loosening (of which is a problem on our machinery), I asked myself why cannot...
Hello All.
This is yet another choked flow thread but worry not for I have searched previous threads to make sure my questions are not redundant.
Before my question(s) is put forward, a brief theoretical background:
A scenario in which two pressure reservoirs are connected with a pipe in...
Hello fellow engineers.
I am tasked to design a complete new suspension system for a concept race car. With no background in suspension design, I am currently in the self teaching/literature review phase (for 4 months and counting). I have done cad models but only as concept designs with little...
I'm currently investigating a dozer/rock-clearer used in the mines to clear blast ore. The problem is that the slope condition in the working area is not only downhill but tilting downwards to the side as-well. Even if the dozer can resist sliding forward it may still have a dangerous tendency...
