A $9\mathrm{.}00$ m long, simply supported beam ABCD is supported by a roller connection at A and a pin connection at C$.$ B is located $3\mathrm{.}50$ m to the right of A$,$ C is $2\mathrm{.}00$ m to the right of B and D is $3\mathrm{.}50$ m to the right of C$.$ A uniformly distributed load of $25$ kg$/$m is applied acting downward between A and C$,$ and a $3250$ N point load acting downward is applied at B$.$

$($a$)$ Determine the magnitude and direction of the support reactions at A & C$.$ Provide your answer in units of N to $1$ decimal place.

$($b$)$ If the point load was moved from B to D$,$ would the beam still meet the definition of a simply supported beam? Show your workings and provide a reason for your answer.
