Hi, I wanted some clarification for how would the reaction loads at end supports and joint will be calculated in the case shown in the schematic diagram. The load of right block structure would be supported by roller A however that load would also be transmitted to roller B. So, how are we going to calculate the load at right and left end support and roller A and roller B. This is a simplified version of structure in actual the structure would resemble a passenger boarding bridge where one column is mobile and can move horizontally and roller basically facilitates the movement. The outer block can move over the inner block. Thank you in advance.
