This is a great question related to engineering mechanics and dimensional analysis. To answer your question, we can use Buckingham π theorem, which states that any physical parameter can be expressed as a combination of independent dimensionless parameters. These independent parameters are called π terms or Buckingham parameters.
In this case, we have five variables, D, h, d, γ, and E, and we want to find the relationship between the vertical deflection, δ, and these input variables. To use dimensional analysis, we first need to identify the fundamental dimensions involved in this problem. These fundamental dimensions can be expressed in terms of mass, length, and time.
The dimensions of the input variables are as follows: - D: length - h: length - d: length - γ: mass/length^3 - E: mass/length·time^2
The dimension of vertical deflection, δ, is length.
Using the Buckingham π theorem, we can form the following dimensionless groups: π1 = D/h π2 = d/h π3 = γh^3/E π4 = δ/h
Note that we were able to form four π terms, which means that we can express the vertical deflection as a function of these four dimensionless parameters. By selecting the most appropriate π term for each variable, we can equate δ to a product of these dimensionless parameters raised to certain powers, ex: δ = f(π1, π2, π3, π4) = kπ1^a * π2^b * π3^c * π4^d
where k is a constant and a, b, c, and d are the powers determined from the theoretical or experimental data.
Therefore, by using dimensional analysis, we can determine the functional relationship between the vertical deflection, δ, and the independent variables, D, h, d, γ, and E.
