It would be very unfortunate if the building you are currently in were to tip over. Answer the following about statics, the science of things that don’t move, for 10 points each.
[10m] Statics studies systems that satisfy two simultaneous conditions: the net force on each object must be zero, and the net of this quantity on each object must be zero.
ANSWER: torque [or moment of force]
[10e] Constraints such as walls may apply this force to elements. This force develops between bodies in contact to prevent them from passing into each other, and it is named for the direction in which it points.
ANSWER: normal force [prompt on reaction force]
[10h] When analyzing a static beam, the first and second integrals of the loading force distribution along the length of the beam give these two quantities. Diagrams of these two quantities are often plotted along with the beam’s free-body diagram. Name either.
ANSWER: shear force OR bending moment [accept shear and moment diagrams]
