Problem 08 : Analysis of the wind acting on a small Hawaiian church, which withstood the 165 mph. winds of Herricane Iniki in 1992, showed the force transmitted to each roof truss panel to be as shown. Treat the structure as a symmetrical simple truss and neglect any horizontal component of the support reaction at A. Identity the truss member which supports the largest force, tension (T) or Compression (C) and calculate this force.
