Q.1. 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.

For the walking-beam mechanism shown in Figure 3, find and plot the x and y coordinates of the
position of the coupler point P for one complete revolution of the crank O2A. Use the coordinate
system shown in Figure 3. Hint: Calculate them first with respect to the ground link 0204 and
then transform them into the global XY coordinate system.
