Angle plates are used for supporting long shafts so as to reduce the bending stresses made within the shafts due to its own weight. Structural analysis of Angle plate by FEA software package ANSYS is given during this report. Loads on the angle plate are because of the load of the portion of the shaft. The maximum stresses are observed at the bolt holes and the bend. The free end has the maximum deformation because it is free to move. The maximum stress is below the yield strength so the planning is within the safe region.

Dynamic loading should be avoided by keeping the shaft balanced. For static loading due to the weight of the shaft portion, the angle plate will be safe. But for dynamic loading, the case may not be the same. In order to keep the angle plate safe from failure, we have to keep the shaft balanced so that no dynamic forces will produce due to the vibration of the shaft. For dynamic forces/fatigue loading the yield strength is considered to become half. The failure of the angle plate will occur by tearing of the upper left bolt hole. The surface of the bolt holes must be polished so that crack sizes at the surface become smaller and offer maximum resistance to tearing.
