One of the most basic connections between structural elements is the pin connection. An axial member, which carries an external force , must be anchored to a support.
In this simple connection, force is transmitted to the pin. The pin transmits the force to the gusset plate, and the gusset plate transmits force to the support column.
In this movie, the normal, shear, and bearing stresses that are developed in the various parts of this connection will be considered.
