I have always heard stress concentrators called stress raisers. I don't think this would qualify as a stress raiser as, apart from the extra force caused by the extra mass, there is no real difference. There may be a case where the dynamic loads are concentrated more towards the fixed ends, but in this case the lower overall deflection probably helps, not hinders, the situation.

I had to look it up, was some gruesome pictures. Then I found one that showed a plank overlapping a joint.

Welcome Check that as you may get reduced VAT. https://www.no-use-empty.org.uk/advice-and-guidance/property-tax-and-vat/reduced-vat-schemes/

Even with my water being the most expensive in the country, that is too high a price. What is this for?

Came across this idea a few days ago. I am sure if properly designed and maintained it would be clean enough. My only concern would be the cost, and long term availability of the filter. https://www.orbital-systems.com/ https://en.wikipedia.org/wiki/Water_recycling_shower Anyone have any experience if them?

£4999.99. A Dutch Auction is an effective way to find out how much cash people have to spend

Good luck getting a reliable flat roof made in England.

I suspect a threshold and parasitic loads.

Is Aircon. Think it is the amount of energy to cool a ton of water 1⁰f.

In the US of A, they measure houses in feet, but oddly don't use fluid oz for volume, they stick to cubic feet per minute. As an aside, when I listen to energy traders/experts on the radio talking about 'the energy crisis', they keep talking about the price of a therm pf gas. And the government uses barrel of oil equivalent in reports. And how often do we hear someone say they use a lot of energy, then say it is "£300 a month". SI and the derived units are so easy to understand.

One problem with drilling into brick or block walls is that you don't know where the joints are, and sod's law means you half hit a brick and a strip of mortar. Another good reason to not build with those outdated materials that the English are so fond of. An old American friend of mine who worked for many years in Architect's offices told me that she had never heard the saying 'as safe as bricks and mortar'.

Yes, but as I said, it is good practice.

Make sure the door is weather tight, you only need to insulate the walls that connect to the house, and you can add extra insulation to the shed ceiling. That just leaves the problem there for the next owner, who may not bother to sort it.

You have to use it to very day. Even then it is easy to make errors.

Or metres even.

I have never understood why, we have SI units to make life simple.

Easy error to make, I usual reduce to a reciprocal and then multiply at the end. Then forget.

Yes, it is just good practice. Wear, between dissimilar materials is proportionate to their hardness difference ratio at low speeds. So if the the knife has a hardness of 10 and the timber is 2, the knife will wear at 1/5 the rate of the timber.

π x r2 = area of pipe 3.1416 [π] x 0.052 [m] = 0.007854 [m²] Flow rate x area = volume per unit time. 0.8 [m/s] X 0.007854 [m²] = 0.0062832 [m³/s] 3600 seconds in an hour. 0.0062832 [m³/s] x 3600 = 22.61952 m³/h For bonus marks Approximate density of air 1.25 kg/m³ 22.61952 [m³/h] x 1.25 [kg/m³] = 28.2744 kg/h. Specific heat capacity of dry air approximately 1 kJ/kg.K So to heat (or cool) 28.3 kg by 1K will take. 28.3 [kg] x 1 [kJ/kg.K] x 1 [K] = 28.3 kJ To convert to kWh, multiply by 0.00027778 (1 / 3600 [s]) 28.3 [kg] x 0.00027778 = 0.007861111111 kWh. As this relates to the flow rate per hour, dividing by 1 hour will give the power, in kW, multiply by 1000 will convert it to watts. 0.007861111111 [kWh] x 1000 = 7.9 W. I think, please check.

Knifes should be sharp edge upwards to stop them blunting.

Can the application show mean import and mean export over a set time period i.e. hours, days, weeks, months, years?

That and TVs.

It is safer to be pessimistic as if you are over optimistic then you have to invent Hopeium. I would have thought that these 'old men' would be the ones to drive the transition. They have the resources, the experience and they like to make a profit. I think the real problem is the general public, they just don't believe that renewable energy is cheaper and does not take up all the farm land.

It is to connect up Hinkley Point. They will probably have to take them down again.

As was established in another thread, they have not been saying that. They want to stop new licences being granted. That is something very different. There is 1628.2 kWh of energy in a barrel of oil, todays price is $90 for Brent Crude (what you want for making gasoline). That is £75. So 4.6p/kWh before transport, storage and refining (and possibly extraction). So once in your fuel tank, a similar price to what I calculated for PV/Storage.
