"Wouldn't a teeter totter do what you want?"
Problem is anything relying on simple levers ends up with the big mass still moving at whatever the lever ratio is times the speed of the small mass.
I think Sneekster is on the right lines. Drop large mass onto spring, use a ratchet to hold the compression in the spring. Roll the large mass off, replace it with the small mass, and release the ratchet.
This doesn't give you 100% of the PE of the large mass because you are also accelerating...
Here we go again. Absolute zero information. Please try falsifying what you have just written. You can't. It's not science it is blather. Gum flapping.
One observation commonly made by skeptics is that the climate cult seems more like a religion than science.
In the steady state the pressure on each side of the piston is equal, but the vent by the base of the spring means that the net force on the piston from the gas, due to the difference in surface area, is resisted by the spring. This opens the ball valve, which allows the pressure on the piston...
Note I've forced BM at tip to be zero, this gives a slightly different curve. Sorry I'm getting this problem confused with another that uses the same script. There's really only 2 load cases w1 and w2, superimposed.
w1 only,
w2 only
and just to check the superimposed solution, with...
Yes that's right the slope from w1 at B dominates the slight change in slope caused by w2 outboard of B
% Given Data
E = 30000 * 1000; % psi (modulus of elasticity)
I = 104.3; % in^4 (moment of inertia)
w1 = 35 / 12; % lbf/in (uniform load on span 1)
w2 = 15 / 12; % lbf/in...
Fror political purposes you are right, weaselly statements are fine. But for engineering and science you need to write in a way that includes testable outcomes, so claiming that something may happen by some non specific future date is untestable, and hence not science. Or as Popper said...
Yes, it doesn't go exactly to zero because the dx value was 1 inch, which is far too coarse unless you interpolate, which I didn't. You can see the lack of resolution in the SF diagram at the rh support.That's a missing area of about 1/2*247 lbf*1", about 10 lbf ft and the residual moment at...
'may' renders the entire sentence devoid of any usefulness. It means as much as This huge pile of energy may not affect climate and may not cause any havoc.
Here's the IPCC in AR6
Trends in precipitation are not a main driver in affecting global-scale trends in drought (medium confidence)...
IDS, you were on the right track, the ends of the first two layers do little initially. If you look at a leaf spring the geometry may seem odd, but the bending stiffness is not far off that of a trapezoidal or triangular plate made of the three leaves lying side by side. Crucially the length...
I can help once the rail starts vibrating, but the excitation mechanism is new to me. This paper seems relevant but I can't download it

Perhaps we need a geoengineering thread. The main issue is that from any given solution (including reducing CO2 in the atmosphere) there will be winners and losers. An obvious example of this is cloud seeding - if the rain falls on my country it won't fall on your downwind country.
