What is the best catapult design?
The Trebuchet: The Trebuchet was one of the more accurate and efficient types of catapult used in ancient times. It worked by using the energy of a falling counterweight to rotate a beam around a pivot resulting in the release of whatever projectile was loaded into the sling at the other end of the beam.
Why is 45 degrees the best launch angle?
As ball speed increases, so does the drag force and the lower is the required launch angle. A launch at 45 degrees would allow the ball to remain in the air for a longer time, but it would then be launched at a lower horizontal speed at the start and it would slow down more because of the longer flight time.
Step 1: Materials & Tools
To build your own golf ball catapult, you'll need quite a few materials that are very cheap and basic hand tools, and chances are you'll have some of them lying around the house.
Step 2: Arms
I wanted to have arms of different lengths because I made this for a science fair project. For the lengths, cut the 3/4'' PVC pipe to lengths of 24'', 28'', 32'', and 36''. Then, drill a 5/16'' hole all the way through each of the arms exactly 6'' from an end of the arm. This is where the fulcrum will be.
Step 3: Arm Supports
Cut the arm supports as shown. The only parts you need to cut are the arm supports. Cut off a bit of triangular excess, and the remnant is the base of the trebuchet - exactly 1'x2'. Drill a hole for the arm bolt as shown, with a 5/16'' bit. Once you've done that, you can test fit the arm and washers by layering them as shown.
Step 4: Attachment & Base
Attach the arm supports as shown with corner braces and screws. Make sure that the arm can still swing freely with no resistance. Then drill a 1/2'' deep hole 2'' from the back and 6'' from each side below the arm and glue in the dowel. Let it dry for 4 hours.
