Week 1 Challenge
1 ans) truss a is know as pratt truss and truss b is know as howe truss
pratt truss is diagonal memebers are arrranged such that way are in tension and their is effective use in material
howe truss are complete oppsite to that pratt truss ,here the position of the diagonal memebers switched as compared to geometry abd the diagonal member,compresion and veritcal members are in tension2
so truss a is most efficient when the gravity loads are applied when compared to truss b

4 ans)the tributary area=tributary width*span of the beam
now ,load on interior beam=10*2*8=160kn
load on exterior beam=10*1*8=80kn
load on interior girder=10*4*8=320kn
load on exterior girder=10*4*4=160kn
