I saw a grey interior one of the review videos.

@cvalue13 @JBee Oh hey guys. Fancy seeing you here. I'm just here to get notifications from the structural exoskeleton crowd.

I should rephrase that for clarity. I don't mean that IF they are epoxied then they CANT be structural. What I mean by that is that if they are epoxied then the additional structural benefit of the steel would be the shear stiffness but it would be limited to the shear strength of the adhesive...

I'm so happy that you posted this. My day job is the structural design and analysis of aerospace structures, specifically carbon composite wings and fuselages for small airplanes. So I've had several people in my daily life ask my opinion on the Cybertruck "exoskeleton" and I have been saying...

I've been off this forum for a while so I'm out of the loop on what the general consensus is here? I came back specifically to see if there was any discussion on this. Seeing the truck in photos over the last few years gave me suspicion that it was not a stressed skin. Now seeing the final...

Sure, if that one criteria out of the list I provided happens to be the actual limiting factor. But for that to be true then you have to assume that you know that all 3 versions have different weights. The motors may have different weights, and so may the batteries. But you and I do not know...

Payload can be defined based on a variety of factors. In some trucks, payload is the difference between curb weight and gross weight, meaning there are no limiting factors other than legal requirements. But with other trucks, you may be limited by power, or transmission capability. Also, there...

1) Stainless. Trucks don't last more than a couple years where I'm from due to rust. The main reason I don't buy new. 2) 3500 lb. payload. I haul thousands of pounds on a regular basis. But a diesel or 3/4 ton gasser isn't ideal for my other hobbies. 3) No paint and thick body panels. I drive...

When looking at objects from about 20' to infinity, there isn't much change in your focus. So looking at a car 50' in front of you and then into the mirror at a car 100' behind you doesn't take much time to focus. But, distances from 0' to 20' require a lot more effort to focus and take a lot...

I'd be curious to know what it's like to drive a vehicle where the mirrors have been replaced by monitors. When looking out your windscreen your eyes are focusing on objects 100' away and when you glance at objects in the mirror at roughly the same distance, your eyes don't have to adjust very...

That picture is showcasing the ability of the truck to automatically lower the rear suspension and lift the front suspension to help reduce the angle of the loading ramp. The truck will never look overloaded (up to it's max cargo load of 3500 lb.) because the air struts will automatically find...

Your statement assumes that the geometry would be the same between a steel part and a cast aluminum part. If that was true then so would be your statement. But that's not how engineering works. They know what the material properties are and they know where the fatigue limits are. Applied loads...

When you ask how strong it will be, are you looking for absolute numbers or just a relative comparison to other windshields? If you just assume all glass is made of the same material, then the curved windshields you mentioned are exactly the same strength as a flat windshield, as far as...

They definitely do check these forums. I don't work for Tesla but I design vehicles and I check public and private forums related to the vehicles I design. On occasion I find reccuring complaints or requests for improvements and will implement them when I can or roll them into larger project scopes.

Being able to melt it would be preferable in my opinion, although I don't have any experience with it. The difficulty I see is that the contact area between the door and door frame is wide, like 4-5 inches wide maybe? And probably a 10 ft perimeter? You'd have to heat all that in a relatively...
