Aircraft Fuselage Aircraft Hull Figure 3 a) Consider two large hull as in Figure 3 above made of foam for Amphibian Aircraft has a volume of 80 m³ each, and the total mass of the aircraft when empty is 7000 kg. Determine how much luggage this Amphibian Aircraft can carry without sinking when landing (i) in the lake which have fresh water and (ii) in seawater with a specific gravity of 1.03. b) Please analyse and give the recommendation on the stability of the aircraft when landing in the water if the luggage compartment has been fully filled. The luggage compartment has been located at the centre of the aircraft fuselage. Hint: Draw locations of centre of gravity (CG) and centre of buoyancy (CB) to support your answer.

Consider a stack of six pancakes. Each pancake is made of 1/4 cup (approximately 60 mL) of batter, and the density of batter is 1 g/cm3. 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…
A crane barge 20 m long, 8 meters wide and 2 meters high loaded at its center with a road roller weighing 100 kg, floats on fresh water with a draft of 1.20 meters (draft is the submerged height of the barge) and has its center of gravity located along its vertical axis at a point 1.5 meters above its bottom. Determine the following: a.) Weight of the barge in kg. b.) Center of buoyancy and the metacentric height from the bottom of the barge. Is the barge stable?
