What is the mass of the diver in if she exerts a torque of 2300 N·m on the board, relative to the left (A) support post?

The plank is in static equilibrium ....the torque at B must be balanced

 

From B perspective

  F * d  =    F3            Fd  =  force of diver = ma

2300  = 3 * ma

              = 3 * m (9.81)            m =  78.15 kg
