What is formula for calculating sample size of a specific population to obtain a confidence level?
n = [((Za/2)sigma)/E]2
n = sample size
(Za/2) = critical value
sigma = population standard deviation
E = margin of error
This formula can be used when you know sigma and want to determine the necessary sample size to establish, within a confidence of 1-a, the population mean to within +-E.
I won't go into the details of explaining it, because the site I myself am reviewing from right now has an excellent explanation, and I strongly suggest reading through it. Visit it here.

What is the formula for calculating force vs displacement?
The formula for calculating force vs displacement depends on the specific situation. In general, the formula is force = k * x where k is the spring constant and x is the displacement from the equilibrium position. For different situations, such as friction or gravity, additional factors may need to be included in the formula.
