The discussion revolves around the equilibrium of forces in a statics problem involving a beam supported by a pin and a rocker. Participants explore the components of forces at these supports, particularly focusing on the implications of the angles and the nature of the supports on the equilibrium conditions.
Participants express differing views on the existence and role of the x component at the pin support A. There is no consensus on whether the x component is necessary for equilibrium, leading to an unresolved discussion.
The discussion highlights assumptions about the nature of the supports and the implications of angles on force components, but these assumptions remain unverified within the conversation.
If there was an x (horizontal) component at the pin support A, then the beam could not be in equilibrium, which you appear to have concluded. So what does that imply about your statement that "there must be an x and y component for the pin support at A"? Is that true?logaliciouz said:hi, for question two on the attached pdf, how would the equilibrium in the x work? From what i understand there must be an x and y component for the pin support at A because it acts at an angle but the support at B only has a y component because it is a rocker.
Since there is no horizontal, there is no such relation. Whether the slope is 3:4 or 1:1 or vertical, or horixontal, or anything, the reaction is still upward of the same magnitude. The slope comes into play when you are considering the design of the support itself, not the beam.logaliciouz said:okay so the horizontal and vertical are not related to each other through the angle of the pin
