Preferably, the connection between the two side plates and the bottom plate is rounded. Problems in elastic mechanics, which are the phenomenon of local increase of stress in an object, generally occur at places where the shape of the object changes sharply, such as notches, holes, grooves, and places where there are rigid constraints. The stress concentration can lead the object to generate fatigue cracks and also lead the part made of brittle materials to generate static load fracture. At stress concentrations, the maximum value of stress (peak stress) is related to factors such as the geometry and loading pattern of the object. Stress concentration at the joint is avoided through the rounding treatment.
