Can get some help understanding this page. Especially the equations part. I appreciate any helpful tips?

Forces Practice Packet Each of the following boxes are in static equilibrium. Draw the forces acting on each of the boxes and setup the force tables. Then write the force equations for each of the following boxes. Then solve for the indicated variable. Each of the surfaces is frictionless. Use g = 9.8 m/s2 1) Tables Equations T2=50 N FN 53.130 T F a W Fa T= W= 2) T 5 kg m 36.870 T= mass of box = 3) T 30 kg 25 kg 300 T= 0 =
