How effective are spears?
A spear can cut, slice, and thrust with extreme effectiveness. It can be used to beat swords and soldiers to the ground. It can even be thrown with deadly efficiency when balanced in the right hands.
Are spears stronger than swords?
Is a spear better than a sword? More often than not the spear is superior to the sword. Spears have more leverage, are nimble, are better against armor, pack more of a punch on the thrust, and most importantly they have more reach. Even an inexperienced spearman can defeat a skilled swordsman.
Are spears still used in war?
As mail armor becomes more widespread and affordable the spear continues to be used widely but may have switched from its use as piercing weapon against the cloth covered opponent to being able to imbed into the mail and force a man back or to the ground or even off his horse.
Can spears penetrate armor?
Both plate armour and mail will very effectively stop a spear. A couched lance can penetrate mail in a cavalry charge, but other than that they're not very good weapons for causing damage through armour.
Why did Romans stop using spears?
Partly because the Roman way of fighting, in close-order formation, shoulder-to-shoulder and in-close contact with the enemy—instead of the Greek way of thrusting from a distance over a shield wall—was more suited to the short gladius than to the long spear.
When did humans stop using spears?
Spears began to lose fashion among the infantry during the 14th century, being replaced by pole weapons that combined the thrusting properties of the spear with the cutting properties of the axe, such as the halberd.
Can you slash with a spear?
You might use the spear to cut, just as a sword can be used as a bludgeoning weapon, but you're not using the weapon in the main ways it was designed to function. I suspect historically that very few spear wounds were caused by lacerations with a spear.
Is a spear the most effective weapon?
Historically, spears have been the best, most versatile, most effective military melee weapons, in all their many forms.
How heavy is a spear?
Spears, in general, about 1 - 2 kg, halberds 3 - 4 kg, but there's quite a bit of range. i recently did some spear length comparations in medieval art, and the length seems to go from a head taller (so, just a bit short of 2 m) to almost three heads taller (3 m).
How far can humans throw spears?
It had been thought that the spears, weighing 760-800g, were too heavy to travel at significant speed with enough accuracy to be used as long-distance weapons. But the team found that the athletes could hurl the replicas to accurately reach a target up to 20m away.
Did Spartans throw their spears?
The Ancient Greek javelin consisted of a small bronze or iron tip on a short shaft, only about three feet in length. The Spartans would throw their javelins in waves for maximum damage. A Spartan warrior would carry up to 3 javelins on him at a time.
How far could Spartans throw spears?
20-to-30-footThe Spartan Spear Throw is the bane of many racers. Often a smaller archery-style foam target and sometimes a target made up of two or three bales of hay, this obstacle is a 20-to-30-foot throw from behind a barricade. It's also the single most-failed Spartan race obstacle of all time.
Are spears the best melee weapons?
Historically, spears have been the best, most versatile, most effective military melee weapons, in all their many forms.
Is Katana better than spear?
Katana is better DPS/damage per hit wise. Spears are very fast and while they don't hit as hard they have reach and penetrate heavy armor far better than the slashing attacks of katanas.
Is spear the king of weapons?
The spear is the King of Weapons because it is the most difficult weapon to defend against. The spear is also called the King of Weapons because of its versatility and power. The spear is long and has a sharp point.
Why did armies use swords instead of spears?
"Spears were too unwieldy, swords allowed for better maneuverability and efficacy when flanking." I can believe that the sword was better for that purpose, but I'm having trouble imagining a line of swords and a line of spears facing off and the swords ending up on the winning end.

Why do some speakers have holes in them?
You may have noticed lots of speaker boxes have circular holes, or sometimes slots, usually in the front or back. What you are seeing are ports, or vents, and this identifies what is known as a bass reflex enclosure.
How does an amplifier work?
An amplifier feeds a signal to two terminals on the back of a speaker. These terminals pass the current into a cylindrical coil of wire, which is suspended in the circular gap between the poles of a permanent magnet.
What does port tuning do?
For this to work correctly, the port tuning is calculated for the specific driver in the specific enclosure. If you swap out the driver for a different type, even if it is the same cone diameter, the box and port tuning will no longer be appropriate and it won’t sound right.
Why do speakers become more directional?
Larger drivers can move more air, but the problem is that speakers become more directional as the frequencies they are reproducing go up. This is known as beaming. As frequency increases, the associated wavelength decreases; speaker drivers usually start beaming at a frequency with a wavelength equal to the diameter of the radiating cone.
Why do speakers have multiple drivers?
While it is true that a single driver can cover almost all the audible spectrum by itself, there are a number of limitations it runs up against. If the driver is small it can’t move much air and will struggle to generate bass at a useful level.
Do you need to know the science behind speakers?
You don’t need to know the science behind speakers to be able to listen to and enjoy them. But if you intend to spend serious dough on audio equipment, it’s always a good idea to first equip yourself with some knowledge. A little base knowledge will help you understand why certain design decisions were made, how they influence the sound, and to help you identify snake oil salesmen.

How does a loudspeaker work?
In this animated diagram, you can see how a loudspeaker works. A stereo or amplifier drives the speaker with an electrical signal that alternates from positive to negative in the shape of the musical signal.
Why do magnets have holes in the center of the speaker?
Some, but not all, speaker magnets have a hole in the center to help ventilate the voice coil and keep it cool.
Why is a speaker enclosure needed?
A loudspeaker enclosure (“box”) is very important for several reasons:
What is a 2 way speaker? What is a 3 way speaker?
2 way speakers use a tweeter and separate woofer, working together, to create the full range of music reproduction. In this type of speaker system, tweeters are supplied only a high frequency sound from a high-pass crossover while the main driver is fed midrange and bass from the low-pass crossover. The result is a very clear & enjoyable sound.
What is the spider in a bobbin?
Spider: the spider is a wavy-shaped thin woven material that supports the voice coil bobbin assembly and helps push the cone back in place as it moves. Speaker cone & dust cap: the speaker cone is a cone-shaped stiff material that’s moved by the magnet & voice coil together to move air & create sound.
What is the coil on a speaker called?
Voice coil and bobbin: The bobbin is a round tube attached to the bottom of the speaker cone. A very long and tightly wound coil of wire, called the voice coil , creates a magnetic field as electricity flows through it from the musical signal from an amplifier.
What type of magnet is used for loudspeaker coils?
Loudspeaker magnets are usually a permanent magnet (usually a ceramic or neodymium type magnetic material) with a thin circular gap in which the voice coil is suspended. The magnet provides a stable magnetic field area that attracts or repels the voice coil.
How do conservatorships work?
When a person is considered to have a severely diminished mental capacity, a court can step in and grant someone the power to make financial decisions and major life choices for them.
