Hi, bloggers this week we made some parachutes to see what design would work best. We had to think like an engineer, we had to imagine, ask, create, and improve. Here is me and my group's work.
first, try
We used String 2 bolts Green fabric cut on corners. We had a fairly big parachute it was 40 cm long and 32 cm wide we made it fairly big because that increases drag, and it will fall slower. We thought that we should add more fabric on the top but we realized that would make it heavier. Our design fell in 1.05 seconds, which isn't very good.
We added more fabric on the bottom of the parachute so it keeps its shape. When falling We saw it fall slower before we changed it fell in 1 sec .5 when we changed it. it fell in 2.00 seconds. We changed it one more time and added more fabric 1.44 it did bad so we took the new fabric off.
