• Identifying and describing action-reaction force pairs is a simple matter of identifying the two interacting objects and making two statements describing who is pushing on whom and in what direction. For example, consider the interaction between a baseball bat and a baseball.
• The Reaction Quotient calculator computes the reaction quotient based on the concentration of two substances and two exponential coefficients. The Reaction Quotient  formula, Q = [P] y / [R] x , is used to calculate the reaction quotient when a reaction is at any state other than equilibrium.Q is always maximum at the neutral surface. However, may or may not be maximum at the neutral surface. Check all possibilities. The shear flow or force per unit length of beam acting on the joint between sections making up a built-up cross-section is given by: where the area on either side of the joint is used to calculate Q.
