Exit Stage Right

The 2nd and last Action Project for Stage Chemistry, a class all about stages in theatre, is already here. In this project, we focused less about what a general stage using our space would be like, and more about how we can directly add certain details, mechanics, or functions to our now determined and measured space. This unit covered different equations on physics such as how many Joules of work are applied with a certain amount of pounds of force is applied over a set difference, and that directly tied into my pulley system which is one of my major details for this set. In the last post (and project), I wanted to objectively present information about the space, but now I have the opportunity to expand upon telling you how my play would work. As you know, assuming you've read my previous post,  this is a play that is based on The Legend of Zelda. Considering the very large focus Nintendo takes on big wide open adventures for one of their leading franchises, and my dedication to stay true to that concept, my biggest challenge for this project was to create or introduce 2 moving parts of the stage. So then, here you can read through my plans for a low-budget adaptation of The Legend of Zelda!

Now when thinking about what I could modify, I realized that the Welles Park Gazebo isn't mine, and of course, it's also open to the public. That said, I didn't want to try and claim that major modifications would be made to the gazebo so my main obstacle was trying to incorporate 2 moving features on my stage that could make up a total of 8 safety hazards for me to review. Once again, public space and being an already established gazebo did not make this task easy, so I had to think very practically, yet also outside of the box. After a while of I came to the conclusion that having a fake horse move on the stage deck would be a perfect decision. But that's still only one of 2 hazards, and what kind of safety rules could I handle or convey. This is low budget after all.
Considering how I wouldn't want to just have another stage deck and call it a day, so I wondered if I could possibly have something inside of the gazebo, which then made me remember that there's a magical floating object with sacred power that often floats in the game, so that encouraged me to think about and utilize a pulley system.

Model & Horse

Now this is the full "stage", the intended focus with a stage left and right on the lines of the path. You may also note the horse present in the picture, which will be a type of prop used during the play as our hero, Link, needs some quick mobility around the land; the horse provides extra immersion and stays faithful in how the games provide transportation.

The horse will be made out of a lightweight material, hollow on the inside, but has some support rods and a bike seat so people may sit on it. Resting on a stage deck, the horse would be probably no more than 25 pounds, and to convert that, one would need to push or pull with a force greater than 112 Newtons to get it moving (as 1 lbs is 4.44822 N, so 25x4.44822 gave me my answer). In person, the horse will measure at 8 feet in length, and 6 feet in height, while the model is 2cm by 1.5cm, as every 1 centimeter equates to 4 feet.

My first though was that this park is public, people may smoke cigarettes, and this horse will more than likely be flammable. So as you can see, there's a no smoking sign that would be a sticker slapped onto the horse itself and it would be nice, large, and most likely on both of the side of the hind legs.

Another few safety hazards of the horse could be that someone could fall off whilst "riding" it. And if the stage  deck supporting it isn't controlled well, it could become a run away tragedy. To prevent any liabilities like that happening, the horse won't go up any slopes or ramps, and we might have some type of handles for anyone who's riding it to hold on to.

Now then, let's talk about the pulley. It's going to only be used for one function at the end, and as you can see, in order to keep the object (known in Zelda lore as the Triforce, which is essentially the combine essence of the goddesses that made the land) stationary in the air, we have a dual pulley system that halves the weight from 8 pounds to just 4. Multiply that by the total distance of the rope and the converter from pounds to Newtons, and you have how many Joules it would take to support the object if the rope had no slack or just was 40 feet long from the pivot point. Now of course, since the rope is so long, we can use picks or counterweights to support the Triforce just out of view with an easier time by simply having the rope used at a closer point. So really, this could have been from a 30 foot mark or as close as it can be to the second and grounded pulley.

But what hazards could come from this simple machine? Well if improperly operated, or if someone accidentally releases or allows the rope to slip, that's an 8 pound object traveling at 9.8 m/s across 25ft of distance, assuming it hits the floor of the gazebo. That's about 890N of force, which is definitely not just a tickle to anyone underneath it. So some makeshift signs, bright yellow and bold, would be at the back of the inside of the gazebo, as well as just behind it where the grounded pulley would be. That ensures that anyone working on the play will at least be aware of the possibility.

So all in all, I've managed to list just about everything I can for how this open and public space could be dangerous, how each piece brought into the stage can be used, moved, and calculated, as well as provide you all with a scale model to see what it looks like. The ratio of my model (cm) to life (ft) was 1:4 and the height of the gazebo may not be the most precise, but it stands at 28cm on the model. In case you're wondering how I made the 3D model, it was created through Tinkercad an online resource which allows users to make their own STL files, nice and easy for 3D printing. Thanks for reading.
