Trusses and Frames (Method of Joints, Sections, Member) Determine the magnitude of the force (in kN) in member FH, GI, GH. Include the negative sign if the member is in compression.   ( Hand written and clean writing please )

Given this symmetrical truss, use the method of sections to complete the following Note: On your FBD draw all internal forces in the positive direction (tension). P Ib P lb P lb P Ib P Ib 3' Plb P Ib 1' В M 3' G A 3' L 3' K 3' 3' 3' H 31 P lb P lb P Ib COLLAPSE IMAGES P = 249 lb

Find 5 internal forces of the truss members, Also Find all zero force member. Thank you.

Identify the zero force members in the following trusses. In each case, state which joint you are looking at and the logic behind why it is zero force member:
