tanks

tanks were invented to be armored from being hit by flying objects or other artillery. through out the years tanks have changed and have many different designs and they all have their good points and their bad points. the first armored tank was actually just a chariot with hardened leather as a roof and walls. the tanks that came after were made of metal such as steel or cast iron in ww2 their were many different tank designs but the Russians had the best design of all the tanks in my opinion because it had just the right amount of everything and was also the first one to have angled armor and it also had very large barrel for large shells, the Russian tanks also went to very fast speeds and had more power then needed to drive it through all of the terrains ww2 could have provided. tanks are still used today and are a very efficient way or protecting our soldiers and giving them transportation too. Today we even have tanks that are built just to take out mines and we also have some that are completely remote controlled. tanks will only get better in designs as the years go on and will become more and more electronic and more controlled. thanks for reading my post and here is a russian tank called the T-34 from ww2.

the electric chair

the electric chair is also a torture weapon. it was used to kill the victim by using lots of electricity and to have the electricity pass through the brain into the body and kill the victim as quick as possible but in some cases this wasn't true because the executioner sometimes would forget or not put enough water on the persons head and there head would simply burn and not actually kill the person or it would kill them but in a cruel way. the electric chair is a fairly simple design and was still used till recently when replaced by poison injections. the electric chair was upon the most common way to kill inmates on death row in prison besides hanging. this is a chair from a prison.

here is also a video explaning on how they used the electric chair.

the rack

the rack was a weapon of torture used by many people and even religious groups like Christians to have people tell them things and if they didn't they would get stretched more and soon enough get dislocated bones and soon enough ripped in half. the rack was basically a table with ropes or chains tied to a spool that would be turned to wrap the rope or chains tighter and start to pull the victims limbs the spools would be turned with long dowels and some tables featured gears so that the spool would not unwind with no pressure was on the dowel. the rack was fear from everyone that had a chance to be the next victim and also some countries adapted the rack and improved the design by adding spikes on the plank so that when the person would be stretched the spikes would roll across the victims backs and sometime pierce the victims skin and this would make the victim be in more pain and maybe say something that the torturer would want to know, here is a normal rack and the second photo is a rack with spikes on it.

flamethrower

the thing that can ruin or destoy almost anything is fire. And when you put that into a hand held weapon you have an amazingly scary weapon in the enemies eyes. Flame throwers have been around since ww1 and have been extremly useful in wars either to burn down buildings or set fire to forests. flame throwers were most commonly used with the germans durring ww2 using flamable liquid under presure and relayed from a hose to a giant gun (does not fire bullets) that has a small flame ignited at the end so that when the contants under pressure are relised it would travel trought the hose into the gun and out the barel into the already ignited flame and be set on fire. the flaming liquid falls on were ever the person is aiming and starts to burn the object. this invention is very destructive and took alot of lives during the wars and also cause city's to be burnt to the ground. here is a picture of a flamethrower


and here it is in action.

crossbows.

crossbows have been around for many centuries and have had a lot of different designs. The crossbow was invented around 500 B.C in Greece. the basic design of a crossbow is that it is a bow mounted to a handle and is shot horizontally. The cross bow can produce much more power (trust) to propel the arrow because it is mounted and the user does not have to hold the weight like a regular bow, he can simple draw the string back and it is caulked and loaded ready to fire when pressing the trigger. the modern crossbows have pulleys on them to ease the draw weight. Many crossbows today have a fiberglass limb, fiberglass has great characteristics of flexibility and strength. In modern cross bow we switched from metal to fiberglass for those reasons and metal under constant stress will wear out and lose its utility after a while. there are tones of different designs but my favorite is the modern crossbows because it has the best of all the designs and will last a long time. this is a picture of the medieval crossbow

and here is a modern design with fiberglass limbs.

bouncing betty (s-mine)

This is a mine invented by germans in ww2. The germans invented this mine to create maximum dammage. To do this they invented the mecanism to propell upwards and after a delay the mine whould get to about the waist height or higher the sudenly would explode and send mass amounts of shrapnel in to the enemie. This mine design killed many alied soldiers durring ww2. The mine is aproximitly 5 inches tall without the fuse, and about 4 inches in diamater. the way this mine was (triped) trigered is that there is a 3 prong presion sensor at the top of the fuse and if weight is put on them it will get triggered. To get the most use of this mine weapon is that the german army developed an attachment to put on the fuse thats whould be relayed to a trip wire so that it would be much more usefull and versatile. here is the design of the bouncing betty




this is how the allies would disarm the mines, at first they would probe with sticks or bayonets and try not to set off the mine then when found they would try to slip a pin( sewing pin) into the safety hole to stop the fuse from getting compressed and setting off after the safety was on they would unscrew fuse and the mine whould be unable to be set off. thanks for reading and keep coming back to read my blogs.

catapult

catapults are the most effective trowing weapon of the medieval times. Catapults were made from wood rope, and skin( animal). the most common and the best of designs (my opinion) is the trebuchet. It has a very long throwing arm with a long cord with animal skin shaped as a pouch, and a pivot point in the middle of it with a pivoting weight at the end. to use this you must put the object you are going to throw in the pouch then release the trip wire and done you have the object flying through the air at great speeds until it reaches your target. here is a video of a trebuchet made in England.



In my 2nd year of high school i had to build a model trebuchet in my construction class and we had a competition on who's can throw the hardest but after having started the build have way through the semester we did not have time to fire it but im sure my trebuchet would have won.
