How does a ballista work for kids?

How does a ballista work for kids?

A ballista's arms are wood, each supported by being spun into the middle of a large rope. The ropes (one per arm) are the springs of the ballista. The ropes are made of animal sinew. When the bow-arms are pulled back, they twist the ropes.

How far can a ballista shoot?

500 yards The maximum range was over 500 yards (460 m), but effective combat range for many targets was far shorter. The Romans continued the development of the ballista, and it became a highly prized and valued weapon in the army of the Roman Empire.

How strong is a ballista?

The largest ballista could fire a 60-pound projectile up to 500 yards. Ballistae could require a crew of as many as eight men. A single ballista crew could launch up to 1,000 missiles in a day.

What is the ammo for a ballista called?

The heavy ballista is a two-handed ranged weapon that uses javelins as ammunition, requiring level 75 in Ranged and the completion of the quest Monkey Madness II to wield.

How does the ballista catapult function?

ballista, ancient missile launcher designed to hurl javelins or heavy balls. Ballistas were powered by torsion derived from two thick skeins of twisted cords through which were thrust two separate arms joined at their ends by the cord that propelled the missile.

How many people did it take to operate a ballista?

Eight people were needed to handle the ballista. The soldier serving the ballista was called ballistarius. The ballista is considered the greatest achievement of the ancient war engineering.

How fast does a ballista bolt fly?

There is evidence that a properly designed Orsova ballista reconstruction with inswinging arms can consistently reach velocities of 300fps (90 m/s) with ~400 gram ammunition and 5000 pound draw weight….Performance of a personal torsion weapon.

Could a ballista destroy a ship?

Even with several of them and magical enhancement, it's highly dubious that a ballista bolt would be able to penetrate or in any case fly much futher than a warship's hull. Ballistae are primarily anti-personel weapons, they do little structural damage.

How does a catapult launch a projectile?

The launch arm is a lever that rests on a fulcrum. The catapult works when the potential energy stored in a stretched rubber band is converted to kinetic energy when it snaps back to its loose shape, moving the catapult arm—and the projectile!

How big is a ballista bolt?

The ballista was brought to a predetermined distance from the target. It was loaded with a 3ft (100cm) bolt or a large stone and aimed just above the walls. It was then fired with deadly effect.

What is the difference between a ballista and a scorpion?

The difference between a scorpion and a ballista is that a ballista is far larger, and needs to be constructed on-site – it can't be moved with horses and be assembled reasonably quickly the way a scorpion can.

How much draw weight does a ballista have?

Performance of a personal torsion weapon There is evidence that a properly designed Orsova ballista reconstruction with inswinging arms can consistently reach velocities of 300fps (90 m/s) with ~400 gram ammunition and 5000 pound draw weight.

What are the pros and cons of a Ballista?

The pros of the Ballista was that it was much more easier to carry around, and could be managed by less people. The cons about the Ballista was that it was made more for throwing arrow type missiles, and didnt throw things as far.

Are there any forces involved when launching a catapult?

A catapult is a launching device that allows us to experimentally observe projectile motion (see Figure 1). Once the ball is launched, the only forces acting are gravity and air resistance. Gravity accelerates the ball in the negative y direction. Air resistance accelerates the ball in the opposite direction of travel.

How do you make a catapult that shoots 100 feet?

Which is better ballista or catapult?

A Ballista is an ancient military siege engine in the form of a crossbow. Typically it was used to hurl large bolts, and had better accuracy than a catapult at the expense of reduced range.

What does the rope do in a catapult?

Rope – stores potential energy by stretching or winding up while it is attached directly or indirectly to the arm; Restraining Rope – it serves as the trigger of the catapult once release; Counterweight – used in other type of catapult.

What makes the projectile go the farthest?

The sine function reaches its largest output value, 1, with an input angle of 90 degrees, so we can see that for the longest-range punts 2θ = 90 degrees and, therefore, θ = 45 degrees. A projectile, in other words, travels the farthest when it is launched at an angle of 45 degrees.

What is a trebuchet catapult?

A trebuchet is a specific version of the catapult that uses a counterweight to create the force to fling an object from a sling at the end of a pole. All trebuchets are catapults, but not all catapults are trebuchets.

What is a torsion catapult?

The Torsion Catapult is a siege weapon from the Middle Ages. It was the long-range weapon of William the Conqueror. Horses were normally used to pull the catapult back, giving it more tension than a crank powered or human powered catapult.

Did ships have Ballistas?

Sure, many ships actually did carry ballistae, though those were normally on the deck rather than inside, but inside is still a deck, just means it's a covered deck.

Is a crossbow a ballista?

A Ballista is an ancient military siege engine in the form of a crossbow. Typically it was used to hurl large bolts, and had better accuracy than a catapult at the expense of reduced range.

What makes a catapult go farther?

Use the tension of bungee cords as opposed to springs to power your catapult. The cords should be attached to the front of the catapult and at the front of the catapult arm. When the arm is pulled back, the tension in the cord will pull the arm forward.

Does the length of a catapult arm affect distance?

Increasing length of the throwing arm, also increases the horizontal distance travelled by the thrown object.

Why is 45 degrees the best angle to launch?

The sine function reaches its largest output value, 1, with an input angle of 90 degrees, so we can see that for the longest-range punts 2θ = 90 degrees and, therefore, θ = 45 degrees. A projectile, in other words, travels the farthest when it is launched at an angle of 45 degrees.
