- Variable density structures and components are very common in engineering. For example, one such component is a modern civil aircraft wing. Even if it might be made out of the same material from its connection to the aircraft body to its tip, it has to include several different sub-components at different positions inside its hollow profile. So, if you want to calculate the total mass of the wing approximately at early stages of a design, you can try to find a scalar function that represents this variability in density and then represent the mass as a surface or volume integral. Even in an early stage of design, even a minimalist, but realistic 3D example would have been difficult to solve in an exam situation. We will certainly handle a much simpler case here and it will be in 2D. This introduction was just to give you an insight on what you try to achieve in questions similar to the following. Let's assume that the areal density of our component increases along y-axis and there is no…Roll a fair die 60 times. Let X be the number of sixes.
