okay so here i've got a t cross section it's held together with nails along the length of the beam here so i know that this is seeing a sheer force of 1600 newtons i know each nail can hold 750 newtons in shear again these nails are along the length of the beam and i want to figure out basically how close do i put the nails so that this thing holds together so i'm going to use shear flow again q which is equivalent to the force per length right so we're going to use that that's the the length between each nail that we're going to to use here and that's going to equal v q over i so the first thing i need to do is find the neutral axis right y bar so i can base everything off of that find the moment of inertia all that good stuff so um so i got two two things here two rectangles here the first one's at 0.1 times 0.05 times 0.2 and then i've got the top one which is going to be 225 is the
