I would agree with Mech_Engineer, I think you'll find that the 1/4" plate will be a limiting factor in this design. Maybe you haven't got there yet, but I think you should check tear out shear on that plate section.

I think you missed the 12 kN in your Fx equation. I didn't go through the math though.

I've used the motorized versions and your intuition is correct. They are at a small angle so that the wheels drive the board into the fence while at the same time push it into the blade. I think an non motorized version would do the same. They don't mark up the board as far as I recall, they're...

Limited experience here, but most regional/provincial/state/national jurisdictions specify the HVAC standards that must be conformed to. As Steamking mentioned. ASHRAE is very common. Furthermore, there are aspects of the design that are left up to the designer/engineer in which case experience...

You can't replace the distributed load with a point load to find the deflection, those are separate load cases and must be treated so as such. You can replace the distributed load with a point load to help find the vertical reactions at the supports.

I will be graduating with an engineering degree (mechanical) in May of 2014. The city that I currently live in is not where I want to stay after I graduate; however, my wife is well established in her career and it makes sense for us to stay here for a year or so in order to save up money etc...

Fall Semester: - Capstone Project - Heat Transfer - Motion Systems Design - Theory of Vibration - Technology and Society (Liberal Studies) - Mechanical Engineering Lab (electronics and measurements)

257Bits was right on. I talked to my father about this last night. He has been a locomotive engineer for about 20 years and he described a similar system. He also maintained that the fire department should have had the locomotive engineer there when they shut off the locomotive. He also...

I think that it is important to be able to sketch an idea for a design or what not by hand. Its the quickest and easiest method to get your point across. Most finished drawings like Steamking said are done on the computer.

Part one is right although 5 significant figures is enough for this calculation. Are you currently taking a mechanics of materials course? Are you familiar with the equation: \sigma = \frac{F}{A} If so, how do you think it applies to part 2?

Just to clear something up: in Canada a technologist diploma is a 2 year program, a 4 year program is a degree. Technologists are very employable in British Columbia. I did the 2 year program and then continued with a degree. All of my classmates got a job after the 2 year technologist program...

In a sense, yeah, you are kind of free to move that line around depending on what you are trying to do. At this stage in the game you aren't trying to select THE material, but rather a family or families of materials. Ill try to show you with an example from a project I was working on. I was in...

I was referring to something that is not introduced until chapter 7: multiple constraints, so it doesn't really apply here. What is shown in Figure 5.9 are simply design guidelines. If you refer to Figure 5.10 you see the guidelines plotted on a E vs p chart with values ranging from 0.2 to 5...

I meant to say p1 = p2.

Your slope and y-intercept come from equating your performance equations: p1 = p1. You re-arrange that equation to obtain: m1 = Cc x m2, where m1 and m2 are your material indices and Cc is called the coupling constant. The coupling constant is the numerical value you get from the geometric and...
