Are small garden bridges only decorative or can they actually function as a cross for a small stream?

Garden bridges are usually made indeed for facilitating the crossing over a stream or a pond in gardens and parks. They can, however, also be used simply as a decoration.
If you need to set a small bridge upon a stream, though, you should make sure it is well made and that it will be able to hold the weight of people crossing it

Why every time i look for garden bridge for new ideas, i get something about a bridge in London?

There is a new project that has just been designed and is waiting to be approved, for a new bridge crossing the Thames in London. This bridge will be called Garden Bridge as the project involves several trees and plants. The bridge will be only for pedestrians and it will be like crossing a garden.
Here are some pictures of the project

4 men approach a rickety bridge at night. They are of varying ages, and as such take different amounts of time to cross the bridge. Since they just have 1 lantern, and only two men can cross at one time...

perhaps the man that can cross longer minute is old.. so u have to carry that person.. so then cross by two's each one of them carry a person that walk slow..and you cant leave one or two behind co'z there's only one lantern

Torch goes to ground side where gas will flow out of it. Use a tig torch 17 if water cooling is not needed or a size 20 for water cooled one.

Dodge ram 2500 4x4 caliper bolts won't come loose

they are usually loctited from the factory,you will have to heaten the bolt,use a small torch,or a good heat gun on the head of the bolt only,be very carefull not to burn the rubbers on the bolts. one of the small solder torches works well,it takes a few minutes each bolt,but you woon't burn the rubbers.

My SIP 30 is not working. It has a normal air pressure light, normal air flow at torch. The torch has all new consumable parts but no spark when activated. Inside the voltages at the torch leads are about...

It has become my experience that the trouble is in the torch head, especially after the torch head has gotten hot during use. Replacing it may solve your problem.

Moniter screen turns dark green on switch on ,why this happens?

it could be an issue with your graphics card, is this a recent issue or a gaming problem?
does it happen all the time?
if always dark you could check your brightness settings etc, or get the backlight checked by a technician.
if the backlight has gone, you will see the screen fine if you shine a torch onto it.

BenQ FP72G 17" LCD Monitor NO DISPLAY but when i shine a torch on the screen, it shows the display. Does anyone know exactly which compoent i need to replace on the Inverter board ? All transistors seems...

The parts list..Here we go again =)
  1. 4x 2SC5705 (can also be 706 as well)
  2. Bridge capacitors (near the transistors) - Replace
  3. Transformers (can be either 4 or 2 used) - Resolder
  4. Fuse link (Marked with prefix FBxxx top middle of the board) - Replace
  5. 2x Diodes (close to transistors, one for each pair.) - Test
Start with those and if you still have issues post back with a photo of your board from both sides.
