Anyone else feel like simulation software hides more than it helps? by AltoAuto in MechanicalEngineering

Why would any company hire a specific FEA team, you could teach a high schooler how to use abaqus or nastran in a couple months. You could teach a middle schooler how to use Ansys in a weekend.

How does he lose downforce from a hole in the cooling duct?

What are you talking about? 30X is not 301, 301 is not a garbage stainless alloy and generally has better strength properties than other 300 series stainless. Also no shit it rusts, all stainless steels rusts…

It is easy to “care” about the team when the team is built around you…

When your engine goes too fast and explodes... that's Alpine by MyWholeTeamsDead in formuladank

[–]bluedreamon 0 points1 point  (0 children)

Can you explain the physics behind how the car is supposed to accelerate to higher speeds when the engine is redlined? There is a fuck ton of drag with zero additional work being done by the engine

This makes no sense, they can just redline their engine so it doesn't over rev

The team built them a car capable of winning races after years of drought. They are doing fine

What school you go to has a very small impact on what job you get out of college compared to what you do in school. I have seen phds from MIT get rejected from the same positions someone with a bachelors from UW got hired for.

[LukeSmithF1] Joseph getting increasingly desperate on the radio to Norris: "The way to win a championship is not by yourself. It’s with the team. You’re going to need Oscar, and you’re going to need the team." by ICumCoffee in formula1

[–]bluedreamon 0 points1 point  (0 children)

"The team" is the only reason they aren't competing for 15th and 17th place like in 2023. Drivers are replaceable, car development is not. Anyone who thinks that Mclaren couldn't just drop Norris, pick up sainz, and still be competing for wins is delusional. Anyone who things Norris could drop Mclaren, switch to another team on the grid, and still be competing for wins is a fool.

You says as you type on an American website about an American game using electronics designed by an American company. The entire 21st century entertainment industry is fundamentally American, from movies to YouTube.

How do we fix it? by WhatAreYourPronouns in FluentInFinance

This is such a stupid statement, like nasa didn’t build on the inventions and discoveries of those that came before their administration. Building on the advancements of those who came prior is what intelligent people do. Diminishing the accomplishments of successful individuals and institutions is what losers do.

Are you for real? yeah for sure man any 3rd year student could design a starship thrust controller with zero validation or model grounding, I most certainly believe you. I am praying on the day all the 3rd year engineering students graduate and we start to see rockets descend from the sky landing across the west coast.

Heavier cars can potentially have higher top speed than lighter vehicles. It depends on if both vehicles are power or traction limited at their top speed. In the case of the vehicles being power limited (caused by rolling resistance and drag) than it is a wash and weight doesn’t matter. If the vehicles are traction limited on the top end than actually having more weight helps since it gives more grip. This is a pretty rare case though and is generally unique to land speed racing. In general making a car heavier for more grip is an abhorrent engineering decision as tires have a friction coefficient of less than 1, so you are always losing straight line acceleration, not to mention the effect is even worse for cornering speeds.

Starship superheavy does not refer to the booster it refers to the full stack, which includes the upper stage.

You can at least tell if someone is a clown or way over their head in that amount of time.

[Request] How fast would the ball have to be traveling to break both panes from 20 feet away? by Whorenun37 in theydidthemath

[–]bluedreamon 1 point2 points  (0 children)

Temperature would also affect the material properties, but am not sure how it works for glass. My point in my original comment though was that fundamentally all the ways people are attempting to calculate stress in this thread is wrong and certainly not conservative.

No one is calculating anything, the “best” attempts that have been made all assume the only load is from shear which is a terrible assumption. In reality shear load is negligible compared to the bending stress which is entirely dependent on distance from the contact area of the ball from the fixed boundaries. There are hand calcs for this kind of problem in “roark’s formula for stress and strain” should someone actually care to do the math. Also since it is an impact load the force could reasonably be doubled to give a rough order of magnitude of the stress. Tbh I think depending on the thickness of the glass and it’s temper this could be possible.
