How do you find the reaction at a pivot when a plank is in equilibrium?

If the plank is in equilibrium, then it's not moving.
If it's not moving, then the forces on it must add up to zero ... otherwise it would
be accelerating.
At the pivot, there are two forces: the weight of the plank is directed down, and
the reaction is directed up.
The two forces must add up to zero.
Can you take it from there ?

What are moments of force?
The moment of a force is the perpendicular distance of the force from a pivot multiplied by the magnitude of that force. So it's the force multiplied by the distance from the pivot. E.g. A force of 8N is applied to a plank 4m away from a hinge ( the pivot) find the moment that the 8N force caused the Plank. Moment = f X d = 8x4 = 32 (newton meters).

Why the reaction mixture doesn't have 50 percents reactants and 50 percents products at equilibrium position?
Chemical equilibrium occurs when the rate of the forward reaction is equal to the rate of the reverse reaction. Take this example:2NO2(g) ↔N2O4(g)At this point of the reaction the rate of N2O4 produced from NO2 is the same as the rate of NO2 produced from N2O4. The key aspect to keep in mind is that the amounts (of moles) of products and reactants at equilibrium is not always 50%/50%. It is usually not.Finding the amounts of products and reactants present during a reaction can be found using Q. Q is known as the reaction quotient. Q can be found like so:Q=[products]/[reactants]reaction quotient =concentrations of products (M) / concentrations of reactantsQ is used to find this ratio at a certain point in time during a reaction (not atequlilibrium)Most likely, you will be given Keq, the equilibrium constant, for a reaction. The value tells you the concentrations of products/reactants at equilibrium. Comparing Q and Keqwill tell you whether a reaction is at equilibrium.Not to get off topic, the answer is that equilibrium does not mean that the reaction mixture has 50% reactants and 50% products. Equilibrium means that the rate of the forward reaction equals the rate of the reverse reaction.

What happens to the amounts of reactant and products after a reaction has reached chemical equilibrium?
The "amounts" of reactants and products DO change in a reversible reaction. What doesn't change is the concentration of these reactants and products AT EQUILIBRIUM. And also what does not change is the total mass of the system.
