The two-dimensional element is extremely important for:(1) Plane stress analysis, which includes problems such as plates with holes, fillets, or other changes in geometry that are loaded in their plane resulting in local stress concentrations. Plane Stress and Plane Strain Equations The two-dimensional element is extremely important for: Coplanar Force - an overview ScienceDirect TopicsSince the body is rigid, all the particles in the body move through the same displacement, v, so that the virtual work done on all the particles is numerically the same.However, for a pair of adjacent particles, such as A 1 and A 2 in Fig. 15.3, the self-equilibrating forces are in opposite directions, which means that the work done on A 1 is opposite in sign to the work done on A 2.

Determine the magnitude and direction Of the force p that must be exened On the free end of the rope to maintain equilibrium. (Him:The tension in khe rope is the same on each side Of a Simple pulley This can be proved by methods of Ch. 4 Internal Forces and Moments - MIT OpenCourseWare2)P and member BD is in tension, carrying a load P/2. The stress in each member is the force divided by the cross-sectional area where I have approximated the area Note well how the dimensions of stress are the same as those of pressure, namely, force per unit area. See Chapter 7 for a crude table of failure stress values.
