Question 3: For the given figure below: Using method of joints, determine the force in each member of the truss by performing the following: a) Draw the Free-Body Diagram (FBD) of joint C and using equations of equilibrium to find the needed forces with stating if it is tension or compression. b) Draw the Free-Body Diagram (FBD) of joint B and using equations of equilibrium to find the needed forces with stating if it is tension or compression. c) Draw the Free-Body Diagram (FBD) of joint A and using equations of equilibrium to find the needed forces with stating if it is tension or compression. d) Draw the Free-Body Diagram (FBD) where all the found forces are shown on joints and members with writing for members if it is in tension or compression. You are required to show your steps clearly and neatly.
