Question

please solve these for me i really dont understand it

02 (a) ) In measurement, what is meant by a problem of definition? Give an (ii) Explain what is meant when two independent measurements are said to (iii) Simple methods for estimating errors generally over-estimate the size example. have a significant discrepancy. of an uncertainty. Explain why combining errors in quadrature is more accurate. (b) A circular aircraft window made from polycarbonate is clamped at its edge and will experience a uniformly distributed load due to the pressure difference between the cabin and the external environment. Specifications for the window are given in Table Q2 below. If the pressure difference during flight is P-75 1 kPa, use the equation below to calculate the deflection, w, at the centre of the window and the uncertainty in this result.
