How many degrees are in supplementary angles? A regular polygon has angles equal to 160 degrees. How many sides must the polygon have? How many sides does a polygon with an interior angle measure of { 120^o } have? How many sides does a right angled triangle have?
If specific angles between adjacent faces (dihedral angles) are desired, then angular springs (and dampers) can be applied. The spring resists deviation to the rest angle between faces and imparts a torque along the edge that attempts to restore the rest angle (Eq. 7.13 and Figure 7.4). Th...
