Why are same class nuts significantly stronger than bolts?

It seems like a class 8.8 bolt will yield before a class 8.8 nut, and moreover a class 10.9 bolt will yield before a class 8.8 nut.

If this is by design, is there a reason for it? By the numbers, it sounds like mixing a 10.9 bolt and a 8.8 nut is the most optimized and cheapest alternative. Is mixing OK?

I work for a company in Arizona called Phoenix Analysis and Design Technologies, that focuses on engineering simulation software, product development, prototyping and 3D Printing. We have been looking for new ways to reach out to the engineering community to share our love for what we do. would there be any interest in an AMA from our Co-founder/owner Eric Miller?

Here is a short bio:

Eric Miller is co-owner of Tempe based PADT, Inc., involved in providing tools and services to companies designing and manufacturing physical products. PADT has been the ANSYS Channel Partner in the Southwestern US for over fifteen years. He started his career focusing on the application of Finite Element Analysis (FEA) and Computer Aided Design (CAD) to simulate turbine engine components. Over the years, he became recognized as an expert user of the ANSYS software tool and in the development of custom software to automate the product simulation and design process.

As a co-founder of PADT in 1994, Eric gained expertise in IT, graphic design, additive manufacturing, database programming, and small business management. As both PADT and the use of advanced engineering tools grew, Eric has supported dozens of different industries with his broad understanding of the application of technology for product development and manufacturing.

Hey I just got my Bsc in (energy engineering/mechanical) and thinking about having a master of science in general mechanical engineering Would that be a good idea knowing that I'm a graduate of GPA 3.2 after too much struggle and extra year and college had to be taken lol So I'm asking you guys ,is that a good idea and what kind of jobs I should looking for after I have my Msc , >>with that GPA and academic transcript I think I will face a hell of problems lol

Study Hours vs. Work Hours, the same?

Study Hours vs. Work Hours, the same?

Hi guys, just wanted to get some feedback on what people thought about the difference in mind expansion pain (stress) you get while studying vs. the mental stress of working.

Is studying 30 hours per week the same physically, mentally and emotionally as working 40 hours per week in a mentally challenging position….

Im an older guy 30 y.o thinking about going back to college for M.E.

I took Calc 1 & 2 and Physics 1 & 2 and rocked them. I work in finance and I really find no meaning or purpose to my work so just trying to get an idea if Ill be jumping into something more stressful.

A (very simple) problem for any actual engineers – i need help. acrylic box

A (very simple) problem for any actual engineers – i need help. acrylic box

Back Story: I work for a laser engraving company and we have recently gained (stolen from another engraving company) a client who wants us to re-create a product she sells. They are simple lidded boxes made of acrylic, bent over heat used to hold whiskey stones. My problem has been developing a template to re-create (close to exact) her product, so we can continue doing business with her. The Facts: Our acrylic is .175" thick, this particular box is around 4.5" D, 3" W, 3" H. We are bending the acrylic over a DIY heated coil setup. Much like this: http://ift.tt/2cHo9pl

The issue: http://ift.tt/2dxvLRv <my template http://ift.tt/2cHn0hG <her product

I cannot seem to get the corner circles correctly placed (or perhaps their diameters are incorrect) because I keep getting corner protrusions from the acrylic bending. Everything else is fine… it's the damn corners.

I can provide much more information and photos of trials.

PLEASE ENGINEERS! lend a hand!
