Pin-Joint Analysis : Direction and Magnitudes of Support Reactions; Load and Nature of Load of Canopy

I need a worked solution for these questions (also attached on the LAST PAGE of the attachement. The first couple pages are just examples. Thanks)

The structure shown in Figure TA 1 is a pin-jointed section of a canopy and carries a single load of 4 kN acting at the lower right-hand joint.

Pin-jointed canopy
Determine the following:
(a) the directions of the support reactions concurrency for the external forces;
(b) the magnitudes of the reactions and the load in each member of the canopy using graphical means;
(c) the nature of the load in each of the canopy members (ie whether a strut or a tie).


Solution Summary

A pin-joint analysis problem is solved. The solution is detailed and well presented.
