P2
. The truss shown in the figure is supported by two pins at
A
and
B
. Neglect the weights of the members and the friction in the system. a) By applying the Method of Joints, determine the forces in all the members of the truss. (Also indicate whether the members are in tension or compression!) b) After finding the forces in the truss members, draw the free-body diagrams of the pins at
A
and
B
, and determine the support reactions there. Note: In solving the problem, take the magnitudes of the forces shown in the figure as Stud. No:
#_(1)#_(2)#_(3)#_(4)#_(5)#_(6)#_(7)#_(8)#_(9)=>F_(1)=2\times (#_(1)#_(2))kN
Stud. No:
#_(1)#_(2)#_(3)#_(4)#_(5)#_(6)#_(7)#_(8)#_(9)=>F_(2)=#_(6)#_(9)kN
