The work of a force acting on a particle as it moves along a displacement is different for different displacements. Among all the possible displacements that a … See more The principle of virtual work had always been used in some form since antiquity in the study of statics. It was used by the Greeks, medieval Arabs and Latins, and Renaissance Italians as "the law of lever". The idea of virtual … See more Static equilibrium is a state in which the net force and net torque acted upon the system is zero. In other words, both linear momentum and angular momentum of the system are conserved. The principle of virtual work states that the virtual work of the applied forces is … See more A gear train is formed by mounting gears on a frame so that the teeth of the gears engage. Gear teeth are designed to ensure the pitch circles of … See more Consider now the free body diagram of a deformable body, which is composed of an infinite number of differential cubes. Let's define two unrelated states for the body: • The $${\displaystyle {\boldsymbol {\sigma }}}$$-State … See more If a force acts on a particle as it moves from point $${\displaystyle A}$$ to point $${\displaystyle B}$$, then, for each possible trajectory that the particle may take, it is possible to compute the total work done by the force along the path. The principle of virtual … See more A lever is modeled as a rigid bar connected to a ground frame by a hinged joint called a fulcrum. The lever is operated by applying an input force FA at a point A located by the coordinate vector rA on the bar. The lever then exerts an output force FB at the point B … See more If the principle of virtual work for applied forces is used on individual particles of a rigid body, the principle can be generalized for a rigid body: … See more
