Totally agree, same thing I said when it came in. Not quite sure who designed it all, but I was basically told to "fix" it. You make some good recommendations! Thanks!

Good points dhenger, thanks for the response. Here is a picture of the setup: This is looking from the rear of the vehicle, forward. There are pins in it now just to see how it looks, but it typically uses a bolt (which as I said, is rarely torqued). The logic behind using the pin over the...

Right, so the plan is to replace the bolt with the pin (which will be loaded in shear). I'm just not sure how to determine how strong the pin has to be. I like your suggestion about the padlock!

Hard to describe in words, but basically it's two pieces: an metal piece shaped like an 'S' on one side of the slide, and a straight piece on the other slide. The bottom of the 'S' meets the straight piece and they are secured with a bolt. The issue with the existing design is that the bolt...

I have a generator that is fastened to a rail/slide assembly that can be pulled out from the vehicle to have maintenance done to it. Someone suggested using a quick release pin (http://www.mcmaster.com/#standard-quick-release-pins/=l17wjw) to secure the generator in place. My question is this...

Hello all, I am collecting requirements for a customer for a small project, and I am hoping someone here might be able to provide some insight. Basically, power conduit needs to be installed in the ground at a site at a depth of 2 feet that connects a communication shelter to a building (this...

All, I have been tasked with writing test procedures for an HVAC system. I searched the web to find a template or example of an HVAC test procedure, but could not find what I needed. Do any of you have an example or know what should be in an HVAC test procedure? Also, could someone explain...

Thank you all for your replies. I have found the heat load in the room and asked the customer the temperature he wishes the room to be, which is 72 degrees F. I'm now contacting the manufacturer of the unit to determine what temperature the air coming into the room will be, so that I can...

Yes, I picked up on the density part =) Thanks!

AbbyNormal, You state that you usually have a high airflow because the load is mostly sensible. How do I calculate what my airflow should be?

All, I’m a recent grad in ME, so my experience with real world problems is limited. I have been tasked with analyzing the HVAC of a server room with an area of about 500 sq. ft. and a raised floor. I don’t have any experience with HVAC analysis, but here is my approach: 1. Determine through...

I took a look at 6.5.15.1, but it looks like it only applies to buildings under 60ft, while mine is about 75.

I'm thankful for all the responses I've gotten to this post. I looked up 6.5.15 in ASCE 7 and used the equation: F=qz*G*Cf*Af. This is giving me a value of about 435 lb, as opposed to me using the force of drag equation: 0.5*rho*wind speed^2*Area of object*Drag Coefficient, which gave me about...

The antenna will be in Tampa Bay, Fl. I'm not really coming up with a new design, but rather telling the customer whether it will hold or not. I wasn't given too much information about wind loads in the area, so I figured I'd assume a hurricane rolled in and they didn't take the antenna down...

Hello all, I am mounting an antenna on a roof of a building, and I am trying to figure out the wind loads it will experience. Once I have these loads I can calculate the stresses on the bolts it is mounted on. Here is my question: How will the angle of the roof (14 degrees) affect the wind...
