Yesterday was great because I wasted my time driving to the track meet at Punahou and not being allowed to run for reasons that made no sense at all. Therefore, I only did one thing this weekend and that was ART (and homeowork)! So I was trying to make this hand made out of nails and screws and stuff but it wasnt working because of some basic physics principles. First of all, the nails didn't stand up by itself nicely because their center of mass wasn't under them the way I wanted them to stand. When I tried to glue them together with superglue, the glue was really bad and falsely advertised its 15 second drying time. I even tried soddering the nails together but the sodder thing must have falsely advertised as well because it still wasn't sticking within an hour of cooling off. The inclines I needed the nails to be made it really hard for the glue and nails to stick together. When we made our FBDs in class, the box would slide down the incline when the mg or the angle of inclination got too high because the force would exceed the amount of friction holding it up. The nails were smooth, by the way, so already their mew was pretty small. Nails are also pretty heavy for glue so that also made them not stick. Some angles I needed the nails to be were really steep so I sometimes had to settle on smaller angles. At the end of the day, however, I got smart and it worked!
