In this video, a numerical problem on static force analysis of a four-bar mecahnism using a graphical method is presented.
These include a link subjected to two forces, a link subjected to three forces, and a link subjected to two forces and a couple. V-2 Graphical Force Analysis The laws of static forces There are a few special types of link loadings that are repeatedly encountered in the force analysis of mechanisms.
Figure 3: Graphical force analysis of a four-bar linkage, utilizing the principle of superposition.
For example, if a complete force analysis of a four bar mechanism is carried out in 10, 20 or 30 degree intervals of the crank link in 360 0
A combination of static and inertia force analysis leads to an important aspect of the estimation of the load carried by different links and pin joints force of the mechanism.
