The discussion centers on the absence of moment restrictions in a structural diagram, specifically regarding a structure supported by a hinge at point C and a bearing at point A. It is established that these supports effectively prevent rotational motion about the x, y, and z axes. Consequently, the focus shifts to balancing applied loads and reaction forces, rather than imposing moment restrictions such as M_AZ and M_AX in the diagram.
PREREQUISITESStructural engineers, civil engineering students, and anyone involved in analyzing or designing static structures will benefit from this discussion.
The placement of the hinge at C and the bearing at A pretty much eliminate the possibility of any rotational motion. All that's left is to balance the applied load and the reaction forces.werson tan said:Homework Statement
the whole structure wouldn't turn about x , y, and z direction , am i right ? why there are no moment restriction in this case(bottom) just in the above case , namely M_AZ and M_AX
