If I understand your image clearly, you've got a couple basic mistakes happening here. First, what do you mean by "doesn't feel right"? Huh? How much less descriptive could you be? You're an engineer, express yourself in terms engineers will understand. Second, the obvious intent of the...

How many times have I given this very same advice?!?! The manufacturer you're interested in has application engineers that are experts in everything about their products. Use their experience and knowledge. They can't put EVERYTHING you would ever want to know on their website. Pick up the...

Are you sure about that weight? Seems excessively heavy, unless you plan on it being sturdy enough for people to walk on. Is that your plan?

Looks very dangerous.

Again - how do I say this nicely? You are over-thinking this WAY TOO MUCH! First - if the actual loads on opposite sides of the wheel are truly unequal, you know that will result in angular displacement. The wheel axis will not remain horizontal. It will rotate about the rail contact point...

Homework not allowed.

How do I say this nicely? I doubt your premise. According to your diagram above, the left side of the top plate is completely unsupported. I doubt it. I'm guessing you actually have four casters in the system. There are two rails, right? And two casters on each rail, right? And those...

It might also be related to mold release process requirements.

You're getting into an area that will require a good understanding of load and moment calculations. Something tells me we should also ask this question: The diagrams lead one to believe this mechanism is suspended from some structure above. 1) Is it in fact suspended from an overhead...

You have a classic situation here. Misunderstandings the functions of linear bearings and fluid actuators contribute to poor system design. Two bad assumptions here: 1) The motions of multiple "uncontrolled" pneumatic actuators that appear identical will be synchronized. Wrong. 2) Linear...

No Homework questions!

Agreed! Just like when Solidworks says it can create animation videos. Yes, it "can". But the voice of experience says you REALLY don't want to try to create a useful video that way!

I have done several SW weldments consisting of sheet metal parts. It can be done. One must be very careful and understand exactly what they are doing. If properly done each sheet metal body will also have its own flattened state. One becomes a master of configurations in the process because...

First off: if the part is only .015" tall, how is anyone going to be able to measure the difference in 43° or 45°? Second: if you want a metal-to-metal seal you should go for as much contact area as possible, which means absolutely parallel surfaces. (Otherwise you are going to damage one of...

You will undoubtedly have speed variations. This is due to the variation in geometry (swing arm radii) as the linkage components go through their paths. The only way to achieve semi-consistent rotary speed from reciprocating linear motion is with a rack and pinion. Include sprag clutches in...

I was once involved in the design of a very large multi-axis water jet system. The X-axis stroke was over 115 ft, Y-axis was close to 40 ft. And just to make it more fun, no single piece could be longer than 20 ft because it had to fit inside a shipping container. We had to maintain a...

What's your quantity? Buy longer and cut them off. Or go to a specialized fastener house, like Fastenal or many others.

I see no provision in the design for any kind of "pre-alignment" of the two engaging components. That could help a lot. Obviously look at the quality of the thread surface finishes. Are they dissimilar materials? (Steel on brass, Stainless on aluminum, etc.) That would help too. Similar...

"This spring tension depends upon the spring constant, which (by the name itself) is constant." I think your understanding of the spring constant may be incorrect. The "constant" means that the change in force exerted by a spring is related to the associated change in deflection by a constant...

I see so many comments/questions on here about "standards". Standards are well and good, and serve a real purpose, but sometimes the driver of tolerances should be in the application - not some standard. On the other hand, until one has enough experience to actually have some judgment on these...
