Consider a simply supported beam subjected to a concentrated load, as shown below.  The beam has two vertical reactions. There is a reaction force at A and there is one at B. Is it true that these reaction forces are equal in magnitude?  

A simply supported beam is subjected to a concentrated load of 24 kN. The beam rests on a pin and a roller at its ends, as shown below.     We can construct the following free-body diagram for the beam.     Select all the correct equilibrium equations for the beam’s free-body diagram.
