The indoor unit of the air conditioner in the figure is used for cooling in a space of 12 m width, 24 m length and 3 m height. It works in a way to pass 6 times the volume of the space through the system per hour. The dimensions of the grille, which is the outlet of the indoor unit, are 80mm x 1200mm. In order for the air expelled from the vent to not directly hit the people in the area, a guide wing, the details of which are given in the figure, is attached to the front of the vent. 6 M6 (Diameter: 6mm) bolts are used to hold this wing in place. Find the normal stress (Pa) on the bolts.

Normal Stress: It is obtained by dividing the tensile force on the bolts by the bolt cross-sectional area.

Pair = 1.18 kg/m3
