A review of the preceding formulas shows that all 

 live-load stresses may be comp formula* (21), (22), 



(23), and (24), except the counter-Union in a vertical port 

 amlthr in a floor-beam hanger. Formula (25) 



it jxwsihle to find readily l>\ trial the position of 

 maximum counter-ton-! i vertical post, and 



(26) gives the value of this tension. The 

 M.MI in the floor-beam hanger may be found by the use of 

 iihus (14a) and (15a) for pier reaction between equal 

 pans. 



If tli.- .-h..rd- ol the IVatt truss are parallel, there will 

 be no counter-teuton in any vertical post. Formula 

 for the stress in a hii/ntal chord member and formula
