If point C is also a pin, the system is statically indeterminate to the first degree. You would have 4 unknowns but the static equations available is only 3. It can be solved by other methods under the topic in structural theory particularly under the topic in statically indeterminate structures.
How in this case Rbx acts as a shear force?
Rb acts parallel to the cross sectional area of the pin, that's why it's considered as shear force.
@@EngrRyeTutorials Here only Rby is parallel not Rbx ?
Both Rbx and Rby lie on the same plane
Rbx is perpendicular to the pin, that makes it parallel to the cross sectional area.
@@EngrRyeTutorials ok Thank You.Now I got it I Was Wrong in Imaginition
What if the point c is also pin? is it soluble?
