A swinging door that weighs w=400.0N is supported by hinges A and B so that the door can swing about a vertical' axis passing through the hinges (as shown in below figure). The door has a width of b=1.00m and the door slab has a uniform mass density. The hinges are placed symmetrically at the door's edge in such a way that the door's weight is evenly distributed between them. The hinges are separated by distance a=2.00m. Find the forces on the hinges when the door rests half-open. Draw Free body diagram also. [5 marks] [CLO 1.2] Mool b ర a 2.0 m B 1.0 m
