transmission tower 02

A truss structure is used to build the transmission tower shown with dimensions and loads shown below. Assuming the structure does not deform out-of-plane, and that none of the members buckle, find the force that each member named in the table below carries.

a	b	c	d	h	$F_1$	$\theta$	$F_2$	$\phi$
1.5 m	3.4 m	2.7 m	5.8 m	9.2 m	5.8 kN	66 deg	3.9 kN	41 deg

Members:
(Denote tension forces with positive values; compressive forces with negative values.)

Member	Force
