I am putting a gate across my driveway which is 14ft between posts on either side. Its going to be wood and all 1x6 and 1x8 lumber to keep weight down. Each gate will be about 7ft long so I was thinking of putting a wheel at the end of both. I live in NH so Im sinking the post hole 4ft and the gate will be 4ft tall. Do I need to use a 6x6 and if so does the hole have to be 18in wide or can I do a 12in hole with a sonotube and concrete?

I have just built a 6 foot fence all the way around my property. To finish it offI need to build a driveway gate. The gate will be 15 feet wide and have two swing gate sections. I have used 4x4x8 foot posts buried approximately 26" and cemented.   I was considering bolting two posts together and burying them at the same depth, but I am concerned that it still may not be enough support. The gates will have wheels on the bottom also.

I'm looking for a way to add a buffer around a PostGIS geometry, but the size of the buffer should depend on size of the geometry. That is, I want each geometry to be enlargened by, say, 5%.  The idea is I'm looking for intersecting geometries, but there could be an error of up to 5% associated with each one which I want to take into account.  Anyone know the best way of going about this?  The database has almsot a million rows, so I'd prefer it to be fairly fast.

A question on how to get the proper slope in a drain.  Let's say you have two section of drain line that must be plumb to each other. To connect these lines by code a 1/4" down slope is needed per foot.  The two section are 8' apart so they need to have a 2" slope end to end.   Fittings are made with the ports square to each other. The port on a 90 degrees elbow is 90 degrees apart. To me, that means the pipe has to exit or enter the fitting at 0 degrees difference to each other.  But, because of the slope there is no way the the connecting pipe can enter or exit the port square and bottom out. They don't make 95 or 100 degree fittings?

In curling, it is often necessary to hit and displace an opponent’s stone to win the end. Olivia would like to hit her opponent’s stone with her own stone. If she releases her stone at the hog line, it needs to travel another 87 feet before reaching her opponent’s stone. Olivia can be off by 11 inches in either direction and still hit her opponent’s stone. Assuming her stone doesn’t curl (change direction), within what angle, $\theta$, to the nearest tenth, must Olivia throw her stone to hit her opponent’s stone?    With this question, do you need to convert the 11 inches to feet, and then solve from there? And since both triangles are the same, do you only solve for one? $11$ inches = $0.916667$ Feet   $\tan (a) = a / b$  $\tan (a) = 0.916667 / 87$  $a = \arctan (0.105364022989)$  $a = 0.6037^\circ$

It's getting hard to find any selection for my old Avanti 12 speed. it currently uses 27 x 1.25 inch tires. Can I put 700c tires without needing to buy new rims?

I'm playing on a SMP server and am trying to use the Nether to link up all my disparate bases around the world. Note in the below, A is Overworld, B is Nether.  I started with one portal (A1, thus spawning B1 in the Nether), and then created another portal a ways away in the Nether (B2), hoping it would be near the main area all the other players congregate. It (A2) was pretty close to where I wanted it, but not exactly. I then created another portal a short distance away (A3), which was where I was hoping A2 would land. I then went somewhere in the neighborhood of 400 squares away from where I initially built A1 (in the opposite direction of A2/A3) and created another portal, A4.   One would think A3 and A4 would create B3 and B4 on the Nether side, respectively. However, A4 linked to B1, and A3 linked to B2. The weird part is, A1 is further from A4 than A1 is from A3.   I hope that made any sense. My question is:  How far away do portals on the Overworld map need to be from each other in order to spawn separate portals in the Nether? Or, what are some ways to ensure a new portal won't link to an existing one?

Me and my friend want to build a basic 101 mob farm, but we can't decide where to put it. He says it has got to be over an ocean, I say it can just be 128 blocks above ground and it will be just fine.  So the question is:    What is the absolute ideal place for a mob spawner?  If we build it 128 blocks above ground do we still need to light up caves? If we dig a 128x128 square straight to bedrock will that make a perfect environment?   Please advise!

I park my bike at work in a rack like this:    At the moment I have 26 x 1.9" knobbly tyres and the wheel just squeaks into the rack. However I'd like to replace these with 26 x 2" Schwalbe Marathons for a smoother ride and better puncture resistance, and these almost certainly won't fit.  What's the best way of putting my bike in this rack if the tyres won't fit, preferably without annoying colleagues by taking up more than one space? So far I've thought of:   using the lock cable to 'tie' the wheel to the side of the rack - possible but a bit of a faff fitting the bike with a kick stand so it doesn't need the rack to hold it upright - not ideal getting the 26 x 1.75" tyres instead - would work but I'd prefer the wider ones for best grip as my ride is partly on offroad paths and a cobbled street (and nothing to do with thinking the wider ones look better, honest).   But are there any other techniques or products I haven't thought of?  (Security of this type of rack is not a big concern, incidentally, as the rack is inside a shed with a code lock.)

I am confused as to when each should be used to solve problems.I am not looking for the answer to this question, but I will include it here so you have all the information about what I am asking about.      A 15.0 kg block is attached to a very light horizontal spring of force   constant 400.0 N/m and is resting on a frictionless horizontal table.   (See (Figure 1) .) Suddenly it is struck by a 3.00 kg stone traveling   horizontally at 8.00 m/s to the right, whereupon the stone rebounds at   2.00 m/s horizontally to the left. Find the maximum distance that the block will compress the spring after the collision.   I see that the idea suggested  is to use conservation of momentum to solve this problem. But I wanted to solve using conservation of energy in the following way:   $K.E =\frac{mv^2}{2}$  $Spring-P.E=\frac{kx^2}{2}$  $KE_i = KE_f + PE_f$  $KE_i - KE_f = PE_f$  Solving the equations, you get  $x = 0.670m$  The correct answer given is 0.387m.

I have only lengths for the sides of an irregular polygon, can anyone tell me how I can measure the area of the polygon? Remember only lengths of all the sides, no angles or coordinates. Few forums mention about trangulation of the polygon etc. But I only have side lengths. Does anybody have any feedback?

I am replacing a door with a pre-hung door including the jamb. The old door was 29 11/16" wide. The new pre-hung door is 28".  Is this too big of a gap?  Should I make it plumb on one side and make up the difference on the other side? Other threads suggest making up space on the handle side, but this is more space than than what other people were asking about. The trim is 2 1/2" so the gap would be covered.

Ripping up 3/4" particle board underlayment over 1/2" plywood subfloor. Running with the joists the floor is flat and level. But running perpendicular to the joists I have high spots every six to seven feet creating a sway of 2 to 3 eighths at its lowest point.   My question is, to level or more importantly flatten the floor, can I lay shingles and 30lb felt the length of the low spots, then screw down 3/4" ply on top in prep for vinyl plank flooring?

I am installing an electrical outlet above a gas fireplace for TV.  I understand that electrical code requires securing the NM cable within 12" of outlet box.  I am curious how one goes about achieving this in a finished wall being that there is really no room to get hand, hammer, drill or screwdriver inside the wall through that box opening.   I am sure this is straightforward for experienced electricians but I have no idea how to go about this.

I need to create a banner that is 18 feet wide by 2.5 feet high.  What would be the best way to go about planning this as it is going to be made in Illustrator and every element will be a vector.  Would my best bet be to create the document in its native size and then scale it down in Illustrator to keep the ratio but reduce the file size?  I've come across this before working at large sizes but not quite this large.

I'm going to be putting pavers over an old slab patio. The current patio has settled and spalled, so I'm looking to pitch the paver patio in such a way that it drains as the original slabs did. In some places that will mean 2" of substrate while 1/2" in others.   It is surrounded on two sides by brick wall, and a third side by pressure treated wood (the side of a house built on concrete tubes). The fourth side is the down hill side. Since there is something constraining on all sides, do I really have to cement the perimeter pavers down, or can I just install again existing surfaces?  I plan on using polymeric sand for the cracks, but what is the best type of substrate to use under the pavers if they are on top of solid concrete? Should I compact the substrate or not?
