Does anyone know, In Bolt Group Analysis Page D1.14 Bruhn, why there is a value Zero added to the Componenet Bolt (C) load equations.
Sum H = 250 + 120x1/1.25 + 0 = 346 lb
Sum V = 250 + 120x.75/1.25 + 0 = -122 lb

Is this  a mistake print error or does it mean anything ?
 

RE: Information required

i think it has to do with presentation ... the calc (as i read) is determining the component of each of the reactions in the H- and V- directions.  if this is right, then it'd've been clearer if sumH = 250+120*1/1.25+0 and sumV = 0-120*0.75/1.25-50, or sumV = 0+120*-.75/1.25-50 ...

Rb1957, Everyone knows H and V are the Horizontal (H) and Vertical (V)components, the question is why do you need to add the zero (0)value.  

RE: Information required

It is a good writing style. Rather an intention of it.


You have three forces acting on bolt (c). You must have three projections on each axis.
One projection in each case is equal to zero.

That's all meaning of the two zeros there.

Thanks, Good reason, but confusing and stupid, no other text book refers like this.
