A lightweight diving board is supported by two pillars. One is at the end of the board and the other is $3\mathrm{.}05$ m away. A $75-$kg person is standing on the board at such a location that the pillar at the end $($pillar #$1)$ of the board exerts a $900-$N force downward. Determine the following.

$($a$)$ distance the person is standing from the end pillar $($pillar #$1)$

Since this is an equilibrium problem, we expect to use the first and second conditions of equilibrium to solve the problem. See if you can write a second condition of equilibrium statement that will allow you to determine the distance the person is standing from the pillar #$1$ end of the board. m

$($b$)$ magnitude of the upward force exerted by the second pillar $($pillar #$2)$
