Source # 1 Things You Will Need to Build a Catapult If you are planning to construct your very own catapult, you initially need the following materials: 3 pieces of sticks or wood approximately 10-12 inches (you can use longer ones if you desire to make a bigger one) 8 pieces of sticks or wood approximately 5-6 inches (Note: just make sure that these pieces of wood are half the length of the 3 longer pieces.) 2 of these sticks ought to be cut at the edge at an angle creating a roof like shape (that’s about 45 degrees) Pieces of screw or nails (or even thumbtacks) A bottle of strong glue or glue gun with glue sticks 1 tough stretchable piece of rubber (much like the ones that are used for slingshots) 2 hooks of about a centimeter in size (the ones that look like question marks) 1 slim metal pole (this one should be of the same length as the smaller pieces of wood) a small container or basket (which will serve as the container of the projectile you want to launch) Making the Catapult If you have all of the stuff mentioned above, you can now start assembling the pieces of sticks or wood by following these simple guidelines: Start assembling the frame of the catapult. The Two Sides of the Catapult Place one of the longer pieces on its side

At this point, screw and glue (you can choose between screws, nails or thumbtacks) one of the sticks with a 45 degree cut at the end of the longer stick. The 45 degree angle cut should be placed in line with the first long stick. This should look triangular, forming a 45 degree angle towards the longer stick Now, connect one of the uncut sticks to the long stick and the 45-degree-cut stick. The end of this stick should be placed squarely with the long stick so that it can stand. This would now form some thing like a letter “A” on its side.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
