2.2.1 Statics
The temperature at which a pure substance changes from liquid to solid at a given pressure is its:
Statics term, synonymous with torque, for the rotational tendency about a pivot or center of gravity equal to force multiplied by perpendicular arm distance.
A force has both magnitude and direction. The quantity used to represent a force is therefore a:
