Maybe I should have been more specific when I was defining failure. I meant failure during the preloading process. I agree with you regarding the loss of preload due to vibrations. I work in an environment in which every screw must be prepared to resist vibrations and it's always annoying. It's...

I'd like to better understand this last statement. I've been reading more about threaded joints and I will try to summarize what I learned. First I will define what I mean by failure so we all are on the same page. Failure would be not achieving the target preload in the joint either because...

It's definitely tempting. It's just that they also tell you in the manual to not leave the batteries unattended anyway. I will reconsider though before making a final decision.

Lots of useful information here. Thank you all. I think I will take two additional precautions if I proceed with this. I will take the battery away from the vehicle. It'd be less convenient than charging it on site but if something goes wrong the vehicle will not get on fire. Specific battery...

I want to buy a car/motorcycle battery charger because it's a very convenient thing to have. Also, for a while, I have wanted to have a simple power source like shown. How safe is it to use it to charge lead-acid batteries from cars or motorcycles? I know the simplest option is to buy the...

I was also confused by this. Here is a related thread. Post #6 from that thread contains the insight that made it click for me.

Here is a related article that might be useful. It covers random vibration analysis in combination with fatigue analysis (Palmgren-Miner) using the results previously obtained from the software. It's using a different software than the one you mentioned but the fundamentals are the same...

You're right. I should focus on the big picture before tackling these details if there isn't a quick and easy solution. I will make a bell crank steering mechanism so that at half the steering angle the condition of the 3 lines intersecting is fulfilled. I will try to make it in a way that keeps...

I would initially be aiming for an Ackerman geometry (or bell crank or similar) but trying to accomplish a true coincidence of the 3 lines within some tolerance due to manufacturing for any steering angle. An interesting alternative I found is to independently feed each wheel with a servo and...

So is the Wiki page just wrong in this instance? I love Wikipedia but I am aware it can be wrong sometimes. I am referring to this segment as Jack brought up. Does a Bell-crank steering have the same limitations? Is there a better mechanism that can really guarantee that, at any angle of...

I did read that page and tried drawing it but then the mechanism didn't do as promised. Or at least, I didn't see it doing as promised. In the following pictures, you can see how the vertical distance is not preserved for different steering angles. Therefore, it doesn't matter at which distance...

I am planning to design an RC car to 3D print it and have some fun. It will mostly be a learning experience with the by-product of having a hopefully fun RC car by the end of it. That will probably force some decisions that might be overengineered and negatively impact performance but building...

I'm still struggling to obtain the dampening coefficient of an axial arrangement as shown in previous posts. There is a somewhat similar problem but simpler in this link. Example 13.4.213.4.2: A Metal Rod Rotating in a Magnetic Field. However, in that example, the area actually changes so I can...

I am pretty sure the method I exposed works for any pdf. Dependent variables are out of the question. Still, I disagree. I think there is still depth to explore. More concretely applied to this case, the two points left in the OP and reiterated in post #4. Solving the inverse problem. Finding...

What do you mean by "you have some level of confidence that the value will be within ##\pm 0.5## of ##2##"? I believe we're misunderstanding each other because you're assuming a normal distribution for the pdf. I think you're assuming that because you're talking about standard deviation and...
