Read more, spew less:Coriolis force doesn't produce torque, therefore it cannot effect rotation ... we use convective force (cross product) pressure force = torque ...
In other words, no, the torque about the center of mass due to Coriolis force can't be cancelled out if the object is in motion in any direction other than parallel to the Earth's axis of rotation.Can the torque about the center of mass due to Coriolis force be cancelled out? Yes, the torque about the center of mass due to Coriolis force can be cancelled out if the object is in motion in a direction parallel to the Earth's axis of rotation. In this case, the Coriolis force will be perpendicular to the direction of motion and will not cause a torque about the center of mass.
Reference: Torque about center of mass due to Coriolis force, is it 0?
What amazes me is that Crick told us he is an engineer. I frankly have an enormous respect for engineers as a group.
I also respect true climate scientists. I however am no sheep.
I have presented many scientists, whose specialty is climate study. I present those who call BS to claims man is screwing the planet. I point out that Earth is not tiny. As a planet it is not massive. However it takes a full day to rotate once. It takes 365 rotations per year. In other words, this baby we live on is pretty damned huge. You can use your best telescope and yet you can see a limited distance. Because it is so huge, the earth curvature is not a hell of a long ways away from keeping you see the adjacent areas. Were you to have a gigantic ruler or level, and put it tangentially on earth, you would fast notice the huge change in what you can see in the distance. You experience some of this when you fly commercially. This to some might seem irrelevant. It is to show you climate is hugely varied. We do live on a planet with a climate. It has many climates. I talked to Professor Lindzen by email years back and hit him with some important questions. I asked him about stories he works for the oil interests. He may have given a talk or two. I don't recall that part of his explanation. But he never in his life was an employee of big oil. He is an academic. His pay came to him from MIT up to the time he retired. He lives on Earth. If anybody should tell us to be frightened, he is precisely the man who would sound the alarm.
He calls bullshit. So why don't you join him and me and call bullshit on this political nonsense?

Try it yourself ... any latitude ... which ever way you swirl the bathtub water, that's how the water will spin down the drain ... if you want the water to go straight down, you'll need to wait a week for all the currents to settle ...
If the tub is nearly infinitely narrow, then the rotation will be infinitely small ... and the pressure drop along the axis of rotation will be infinitely small ... which instantly condenses water vapor and releases that 2,100 J/g of energy ... all within an infinitely short time period ... if we then let time pass, then some of this latent energy will be applied to increasing the angular momentum of the rotation ... why cyclones spin ...

Thanks for the question about Density Altitude.Chick is a liar ... she's not an engineer ... I've taken a few college science classes and Chick has never ... there's a couple of things every lab section goes over, every time, that she misses, completely ...
Scientific Theory is nothing without a demonstration ... in the laboratory ... and this is completely lacking in the Hysterical Climate Change movement ... at most, 1,000,000 ppm gives a +5ºC increase ... by ratios, we should see 0.005ºC increase for 150 ppm increase ...
We don't measure temperature that accurately ...but YOU CAN HELP ...
Tell us how you use temperature to calculate density altitude ... say Aspen, Colorado (7,800 ft), on a 95ºF day ... how many extra loops should you fly to get over those 12,000 foot ridge lines all around you? ...
What I am talking about is the fact that air is not naturally moving. It moves when a force is applied. And as you mention, the closer to the two poles you are, the more you notice the wind is not moving in the path the earth is spinning but it veers off to the observer on the ground. Birds paths change due to the effect. When they shoot missiles, they must understand this as part of the aiming process. Of course we are in the era of computers so they will program the missile to follow the desired path. Birds do not have computers so they do it the old fashioned way.Coriolis force is a pseudo-force ... it's strictly an artifact of your frame-of-reference ... shoot your cannon ball due north, so you see the Coriolis acceleration? ... now, where did the kinetic energy come from? ...
From an inertial frame-of-reference ... the Coriolis force cannot be observed ... therefore, it cannot be ascribed to have done any work ... it is you who are under acceleration, not the cannonball ...

I agree. True engineers look at everything available to them, test any theory and then confirm that theory with empirical evidence.

WRT to Coriolis? Where was that?Notice that I did not bring up water spin. I focused on climate.
I'm sorry but I missed that. Can you point it out for me?The impact the spin of the earth has on global climate.
The issue of man made global warming is a GLOBAL one.It has been a few months but I have also brought up a global presentation showing that different parts of earth have some huge changes in climate in relation to other parts.
Let me illustrate. Where the Sahara desert is, we can postulate, accurately of course, that it is a dry region that approximates the size of the United States of America. It has a climate that is drastically different from say Canada or areas north of Canada and areas south of Argentina. We do not find snow on the Sahara desert. Plant life there is unique to this hot area. Check out Death Valley, one of my favorites where even inside of CA, you see vastly different climate in the southern area than say where Santa Rosa north is like. Redwood trees do not grow south of a sort of demarcation point that is in northern CA. If they are planted in the South of CA, and surely some must be there, it is not mentioned. Because they are not natural of the South.
That is a factor that has been brought up but that is not what the fight on this forum is about. It is about whether or not anthropogenic global warming is taking place and, if it is, whether or not it is a threat that requires a response. And, if that as well, what that response could or should entail.Anyway, the huge fight on this forum is do you want you, your children, your family, your friends ... to be blamed for climate or not?
No one is suggesting any such thing.Will you tolerate a Government that persists on knocking you down and changing your life on the premise you are the party changing climate?
Would you go along with taking rational measures to deal effectively with an actual threat facing every one of us?I say hell no. I will not go along with a Government doing this to me, my family and friends.
Nope, and you still can’t prove it. It’s clear you have no clue about the equator. And the northern hemisphere is much more influential.The issue of man made global warming is a GLOBAL one
Here is the thing. Pilots get training in the use of the calculator used to compute density altitude.Oh no ... shit ... you mean I GOTTA FLY THIS THING ??? ... that means we're dead ...
My brother soloed before he could drive a car ... if we paid the rental, he was more than happy to fly us around ... and that included lessons, but I'm a father and have pictures where my money used to be ...
What threat do you control?WRT to Coriolis? Where was that?
I'm sorry but I missed that. Can you point it out for me?

Prove for us that anything I have ever posted here was a willful lie.Chick is a liar
Reiny doesn't like me because I've embarrassed him on several occasions by correcting his mistakes. In response he has hysterically screamed at me, accused me of lying and consistently calls me by female pronouns.... she's not an engineer ...
A conclusion for which he has no evidence.I've taken a few college science classes and Chick has never ...
Every lab section? How would have "taken a few college science classes" inform him of that?there's a couple of things every lab section goes over, every time, that she misses, completely ...
There are lots of fields in which it is not always possible to create meaningful laboratory simulations. Cosmology, astronomy, theoretical physics and so forth. Climate theory is one of them. You cannot create a simulacrum of the Earth's climate in a laboratory. What can be created there has been. If he would care to identify the process he believes can and should be demonstrated, we could talk about it. But he hasn't so far, has he.Scientific Theory is nothing without a demonstration ... in the laboratory ... and this is completely lacking in the Hysterical Climate Change movement ... at most, 1,000,000 ppm gives a +5ºC increase ... by ratios, we should see 0.005ºC increase for 150 ppm increase ...
This is an old claim of some deniers. They believe that the average of a 1,000 temperatures recorded to a tenth of a degree may only be quoted to a tenth of a degree. I have demonstrated on multiple occasions that this is false.We don't measure temperature that accurately ...but YOU CAN HELP ...
