Physic reflection What was the goal of this project? Did you achieve it? Why or why not? Originally the goal for this project was we will have three side, three double sticks will be main support and each side will have six X helping support inside, but sadly we didn’t achieve the goal, the reason why we didn’t achieve it will be we run out of the sticks, and glue, but I think it’s our fault, maybe we didn’t plan it well in the beginning time, and we kind of waste and break some of the sticks while we making it, so we are forced to change our plan, when we build the third side, instead of making six X support we making three triangles in the third side to support it, but we didn’t

When you look at our tower we have 2 triangle in each X, we have 6 big triangle in the first side, about six triangle in the second side, and three triangles in the third side. Also the Newton’s third law we learned recently. “Whenever one object exerts a force on the second object, the second object exerts an equal and opposite force on the first.’’ When we start to test how many weight can the tower hold. The force that weight exert on the tower will be equal to the force that tower exert on the …show more content…
When we start to draw on blue print, the length and the height of the tower should be exactly measured out, and write the unit as cm. Also the degree of angle should be exact, for instance the angle in a triangle should be add up to 180 degrees. The angles in a square should be add up to 270 degrees. When we start to construct it, the glue take a lot of times to dry, otherwise before the glue dry, the sticks always move around, it always not stay in the position that we expected it to be. And the X and triangle inner support part, the inner part should be perfectly match the width of the outside part, too long it’s going to break, to short iss totally useless. What would you have done differently? Use of time, building techniques? If I would have done something differently, I will not choose X as inner support force, I’ll rather choose triangle as inner support, because it saved our sticks and glue, also can make the tower lighter. The time doesn't matter, I think we just have to finish with build the tower in the amount time that teacher given, then it should be fine.
Did the teacher provide enough guidance during the project why or why
