Aperson carries a wood plank of l = 2.6 m long with one hand pushing down on it at one end with a force f1 and the other hand holding it up at d = 0.40 m from the end of the plank with force f2. if the plank has a mass of 21.0 kg and its center of gravity is at the middle of the plank, what are the forces f1 and f2? apply the first condition of equilibrium: net force = 0, to obtain first equation. apply the second condition of equilibrium: net torque = 0, to obtain second equation. (notice: you choose an axis of rotation and mark it on the drawing. the lever arm for each force is from your chosen axis of rotation.) force 1 magnitude (in newtons) is enter a number n (5 attempts remaining)input 1 status force 2 magnitude (in newtons) is
