What is the best catapult for distance?
The onager catapult is almost identical to the trebuchet, but instead of a falling counterweight, it uses a torsion bundle to rotate the arm (similar to the mangonel, described previously). Because of its design, it allowed for greater throwing distance than the mangonel (comparable to that of a trebuchet).
How far can a small catapult shoot?
Catapults can launch things a fair distance -- 500 to 1,000 feet (150 to 300 meters) is common. It is surprising how much energy they can store. The gears are important, because they create a winch. The winch allows a person to put a great deal of energy into the catapult over a period of time.

What is the maximum distance a catapult can throw a projectile?
Dart-throwing catapults were, I kid you not, used to snipe individual soldiers off of fortification walls from far beyond bowshot (the longest range attested for a dart-thrower is 700 yards; the longest achieved by modern reconstructions something like 400—still way beyond the effective range of any bow ever made).
What catapult shoots the farthest?
A trebuchet (French: trébuchet) is a type of catapult that uses a long arm to throw a projectile. It was a common powerful siege engine until the advent of gunpowder. The design of a trebuchet allows it to launch projectiles of greater weights further distances than that of a traditional catapult.

How does the length of the arm affect a catapult?
How does the length of the throwing arm affect the horizontal distance travelled by an object that is thrown from a catapult? Increasing length of the throwing arm, also increases the horizontal distance travelled by the thrown object.
Pneumatic Golfball Cannon- Shoots 450+ Yards! - Instructables
Here I will teach you how to modify the sprinkler valve for pneumatic actuation. You should find all the materials at Home Depot. You'll need a: 1" sprinkler valve 1/4" brass nipple 1/4" blow gun Epoxy Teflon tape Step 1: Take all the screws out of the lid from the sprinkler valve and then pull the lid off. Leave the rubber diaphragm in place and make sure you don't lose the spring.
Step 1: Materials
To build this catapult, you will need some of the following materials. Keep in mind these can be variable depending on what you have available (i.e. arms to pivot on, drill sizes, etc). Five 2-foot planks of wood (pref. 2x4) Two 3-foot planks of wood (pref.
Step 2: Building the Base
First, take one of the three feet pieces of wood and lay it out straight. At this point you'd have two options; you can either connect the pieces of wood directly with screws, or you can connect them with braces, again using screws. We recommend using braces as it is likely to make your catapult more stable.
Step 3: Building the Arm House
The "arm house" is the part of the catapult that holds the pivot arm (a metal pole in our case) as well as the "stopper" which is essentially the most important part of a catapult, as it transfers energy from the arm to the ball ( think of inertia and moving cars, what happens when you get into an accident?!). To start with, you're going to need to place the third two-foot piece of wood standing straight up off of one of the three-foot pieces of wood, as can be seen in the attached picture (yes, it's a duplicate!) Place it approximately in the middle of the three-foot piece of wood. Screws will not work here, you NEED metal braces for this point; screws would either be too long and protrude from the bottom, or would be too short and be ripped form the wood upon impact of the arm. Do the same for the other three-foot piece of wood with the fourth two-foot piece of wood.
Step 4: Constructing the Arm and the Spring Holders
Depending on what you chose to use for an arm, this step may differ slightly or completely for you. To build a replica of our catapult, keep reading. You're going to need another two-foot piece of wood to use as the arm.
Step 5: Tighten, Seal, and Finish
Make sure you go around and ensure that no pieces of your catapult move too easily. You can tighten or slightly modify in places where you need to, just make sure everything is stable! Next, you're going to want some form of arm-stopper-protection. As you can see, we use duct tape.
Step 6: Launch Day!
Now that everything is connected, secured, and finished up, you are able to launch your golf balls.
What is the best way to build a catapult?
Stack five craft sticks together and wrap a rubber band around each end.
What makes a golf ball fly farther?
However, golf balls usually have backspin. Because of this, the air moving over the top of the ball moves faster (relative to the ball) than the air moving under the ball. This lower pressure air above the ball helps generate lift, a force that pushes the ball upward, helping it to travel farther.
How can I get more distance from a catapult?
Use Bungee Cord Power. Use the tension of bungee cords as opposed to springs to power your catapult.
How do you build a simple and basic catapult?
Stack 2 craft sticks together, and wrap a rubber band around the very end. Separate the 2 craft sticks. Place the stack of 5 craft sticks between the 2 craft sticks. Wrap a rubber band around all of the craft sticks to hold the catapult together.
What type of simple machine is a catapult?
A catapult is a type of simple machine called a lever. A lever is a bar centered on a turning point called a fulcrum that’s used to raise or move weights. Levers make it easier to lift heavy things, like a person or a seesaw.
Why do I hit my 3 wood farther than my driver?
Players who hit their 3 – or 5- wood as far or longer than their driver are typically using too little loft with the driver for their clubhead speed. In contrast, with the driver, you have to match the loft angle of the clubhead to the golfer’s clubhead speed to get the most distance.
Do heavier drivers hit the ball farther?
The mass of the club head including the mass of the first 4 inches of shaft attached to the club head is the only mass that will affect the ball at impact. All other things being are equal, the heavier the mass of a clubhead plus the first 4 inches of shaft, the more ball speed (and thus more distance) will be created.
Step 1: Cut Your Pipe
With your saw, you will need to cut the following length in your 3/4" PVC pipe
Step 2: Put Together the Throwing Arm
Put the T joint on one end of the long 27 inch pipe part. Next put the 90 degree joint on the other end. Attach the small bucket on the end of the 90 degree joint. You can do this a screw. I drilled 4 holes in the bucket and put 2 zip ties to attach it and a screw through the middle.
Step 3: Putting Together the Frame
Place a 90 degree elbow on one end of a 31 inch pipe. Next, place 2 T joints on the pipe and center them. This is for the middle (sturdy piece) to keep the catapult up right and the upright piece keeps the catapult aligned. Finish this off by placing a 90 degree elbow on the other end. Repeat this same step on the other 31 inch pipe.
Step 4: Finishing the Frame
Finish off the frame by attaching the two 15 inch pipe pieces at the ends of the 31 in pipes and attach the throwing arm in the middle to the T joints.
Step 5: Finishing Off the Construction of the Catapult
Place the two 12 inch pipe pieces on the last two T joints in the middle so they stand upright. Connect the top with the last 15 inch pipe to the T joints on the 12 inch upright pieces.
Step 6: The Last Step
Cut the hooks off the ends if you are using a bungee cord. Tie the cord to the horizontal upright and around the throwing arm. I used zip ties to secure the bungee cord.
Step 2: Connections
cut 2 pieces off of the 2" pipe about 2" long pipe to use to connect the water vavle and the Y to the reducers
Step 3: Fillin' Station
Attach the quick connect to the gas valve. use teflon tape or pipe dope to get a good seal. thread that into one of the reducers and that into the strait end of the Y. thread the preasure gauge into the other reducer and put that into the other branch ot the Y. using one of your 2" pieces attach the Y to one of the 2" to 4" reducers.
Step 4: The Business End
Glue the 2" pipe in one end of the water valve and glue the remaining 2" piece on the other end. on that piece glue the 2" to 4" reducer and then the 4" pipe
Step 5: IT LIVES!!!!!
Glue the two pieces together and then put extra glue on the out side of all your connections just to be sure. be sure to let it dry for a few hours. we shot ours while it was still wet and my friend almost broke his thumb when the end came off.
Step 6: Ready, Fire, Aim
there's really no way to aim so you just gotta point and shoot. MAKE SURE to not shoot it at anyone or any thing that is alive. it will drive a golf ball through a 1/2" of sheet rock. a wash rag is needed to keep a seal around the golfball.
