| Summary: | A method for calculating the frame of a gravity roller rack for boxes based on the disclosure of the static indeterminacy of the system using the equations of three moments is proposed. Unknown reactions from the intermediate supports that provide the overall rigidity of the structure are determined. The maximum bending moments along the length of the entire roller bar are found, and statically definable systems of intermediate supports, front and rear crossbars, and side profiles are calculated. A method for selecting cross-sections of profiles is proposed and their maximum normal bending stresses are calculated, which are compared with the permissible ones. |
