KNOW WHAT NOT TO DO IN CASE OF A SNAKE BITE !!

Getting bitten by a venomous snake can be very scary, and can lead people to react in exactly the wrong way: Maybe they panic, try to catch or kill the snake, or apply ice or a tourniquet to the wound, which can be disastrous in certain situations.

So, what should we do in case we are bitten by a snake? In this article we will discuss what to do and what NOT to do in case a person is bitten by snake.

All snake bites require medical attention, even if the snake is nonvenomous. Proper wound care can help prevent infection and limit how severe the injury becomes.It is vital never to assume that a snake is nonvenomous without first consulting an expert. The mis classification of snake species could be fatal.

SYMPTOMS FOR SNAKE BITE:

Usually, people know right away if a snake has bitten them. However, these animals can strike quickly and disappear before people have time to react.

Most snake bites can cause pain and swelling around the bite. Those that are venomous may also cause fever, a headache, convulsions, and numbness. However, these symptoms can also occur due to intense fear following the bite.

WHAT TO DO:

• Get to an emergency room as soon as possible. Even if the bite isn't poisonous, you’re at risk of tetanus, a serious bacterial infection, if your shot isn't up to date.
• Move the limb where the bite happened as little as possible. This will help slow the spread of the venom.
• Take note of the snake’s appearance. Your description will help the doctor identify what bit you. (Your location will also be a clue.)
• Note the time the bite happened so the doctor knows how much time has passed.
• Remove any jewelry around the area of the bite before swelling begins.
• Use Tylenol for pain, if needed.

  WHAT NOT TO DO:

• Do not pick up the snake or try to wrap it up or kill it, as this will increase the chance of getting another bite. Even a dead snake is able to bite.
• Do not apply a tourniquet.
• Do not cut across the site of the bite marks.
• Do not try to suck out the venom.
• Do not apply ice.
• Do not immerse the wounded area in water.
• Do not drink beverages with caffeine.

In most cases, it is necessary to remain in the hospital for up to 24 hours in order to monitor blood pressure and overall health.

KNOW WHY THERE IS BULGE IN EXHAUST PIPE OF DIRT BIKE !

Dirt bike engine uses two stroke gasoline engine.The exhaust pipes of dirt bikes are shaped strange. They expand into a wide diameter and then shrink down to a very small diameter where the exhaust gasses emerge into the environment.In this article we will understand why these exhaust pipes are shaped in that manner.

That bulge is called an expansion chamber, and it is used to increase the horsepower of the engine . This technique only works on two-stroke engines, which is why you see it on a lot of dirt bikes but not on street bikes. Most street bikes use four-stroke engines.

The basic idea behind an expansion chamber is to use the momentum and pressure of the exhaust gases to create a pump that squeezes more air and fuel into the cylinder during the intake stroke. It does the same sort of thing that a turbocharger does, but it does it without moving parts.

How it works:

While moving downwards after ignition, the piston exposes the exhaust opening, and the burned gas streams into the exhaust pipe like a (high pressure) shock wave.

Due to the inertia, this gas will create a slight vacuum wave behind it, which helps to suck out more burned gas, but also fresh gas as soon as the intake opening is uncovered. 

The first cone helps to increase the vacuum: When the gas travels through the pipe with a certain speed, it travels through a certain volume per time. If the cross section is increased and the speed remains the same, the wave travels through a larger volume. This creates more vacuum volume behind the wave.

Now we have fresh gas in the cylinder, but also in the manifold. The shock wave now hits the right cone and gets reflected.That is, you now have a shock wave running towards the cylinder. It hits the fresh gas right in the moment when the intake opening is covered by the piston, and presses this gas into the cylinder. When the piston covers the exhaust opening, too, the fresh gas already is under some pressure.

This way, the exhaust forms some kind of compressor, increasing the volumetric efficiency / power of the motor.

KNOW WHY MANHOLES ARE ROUND IN SHAPE !!

You might have noticed that most manholes, and their covers, are round in shape.We will discuss the reason behind the round shape of manhole cover in this article.

1.Mishandling the Manhole cover-A round manhole cover cannot fall through its circular opening, whereas a square manhole cover could fall in if it were inserted diagonally in the hole.

2. Rolling the Manhole Cover -A round manhole cover is easily moved and rolled.

3. Strongest shape-When a square or rectangular manhole cover is subjected to sudden vertical compression (think of a very heavy truck driving over it), the weakest spot, the center, isn't equidistant to all supporting sides, especially the corners, which give support from two directions and are thus the strongest points (for similar reasons, experts recommend you stand in the corner of a room during an earthquake). With a circular cover, the center is equidistant from all supporting sides, and due to the gradual curve, any point along the edge gives almost as much support as a corner on a square cover. Circular shape results in uniform stress distribution.

4. Circular covers don’t need to be rotated or precisely aligned when placing them on the opening.

5. Round tubes are the strongest shape against the compression of the earth around them, so the cover of the tube would naturally be round as well.

6. It’s easier to dig a circular hole.
