Q. A uniform beam (EI=constant) PQ in the form of a quarter-circle of radius R is fixed at end P and free at the end Q, where a load W is applied as shown. The vertical downward displacement, δp, at the loaded point Q is given by: [tex]{\delta _p} = \beta (\frac{{W{R^3}}}{{EI}})[/tex]. Find the value of β (correct to 4-decimal places). __________
