Consider the pancake at the bottom of the stack. What is the total weight of pancakes sitting on top of it? Express your answer in kilograms, but without entering the unit. This is not a lot of weight. Assuming that pancakes have an elastic modulus of 20 kPa, that the area of each pancake is identical (approximately 80 ), and that the stack of pancakes has a height of 55mm, compute how much the single pancake at the bottom of the stack is compressed by the weight of the pancakes on top of it. This is a very small compression, so instead you place a 4 kg weight on the pancakes. Now you see that the stack noticeably compresses. Consider the stack of pancakes as one aggregate unit with a surface area of approximately 80 cm2. What is the stress on the pancakes? Express your answer in Pascals, but without including the unit. Your observation of the normal…
