Reaction forces for a hinge
WebNov 18, 2024 · For a hinge, any force vector F in any direction can be a constraint force, since no movement (translation) is allowed in any direction. On the other hand, the reaction moment vector M on the hinge must be perpendicular to the pivot axis z. This condition is often expressed as M ⋅ z = 0 where ⋅ is the vector dot product. WebMar 30, 2024 · Hinges are in no way special with regards to external moment (indeed, nowhere is). So external moment (and other forces) is useful to know whether the …

WebMay 17, 2024 · The short answer is because there is a net torque about the hinge pin caused by two equal, opposite, and parallel forces which constitute a force-couple, or simply a "couple", resulting in no net force on the bar. From the free body diagram (FBD) of FIG 1 below, the sum of the horizontal forces is $$\sum F_ {H}=R_ {H}+P-P=0$$ $$R_ {H}=0$$
