Pyramid


Hey guys, another week gone by and I’m Still alive!! This week we had a bullseye challenge for immortality. Sadly, no one from either AP Physics class fulfilled the task, but my group (Greg, Dylan, and David) was soo close! Doc said there’s only one chance at immortality though. ☹
My girlfriends and I made a pyramid the other day of ten girls! It was difficult but we ended up finally getting it almost perfect. We were able to complete the pyramid because of weight and normal force working together. The smaller girls don’t go on the top of the pyramid just because they’re lighter, but because they’re weaker. The bigger and stronger girls can handle a greater weight on their back. The bottom row in the middle is where the greatest normal force is exerted, whereas the Jill, the girl on the top, is where the smallest amount of normal force exerted. The normal force of Jill is equal to her weight (mass x gravity). The normal force of the two girls in the middle (me and Mahina) our weight plus the weight of everyone we’re carrying.
