If it is known that the center pin A supports one-half of the vertical loading shown, determine the force in member BF. The force is positive if in tension, negative if in compression. 6 panels at 12 m- 17 m G. 13 m 7 KN 7 kN 14-KN 14.kN 7 kN 7 kN

Determine the horizontal and vertical components of force at pins A and D.

Determine the forces in members AB, AC, and AD. Forces are positive if in tension, negative if in compression.
