u increase travel, head tube angle decreases. less vertical, more horizontal. so instead of the force going from tyre>fork>stem>handlebar, more of the force is absorbed by the headtube compared to a steep angled headtube.
another thing is torquing. longer fork, more torque acting on the headtube, more stress. because usually force from the tire is never in the same angle as the headtube, there will always be torque acting upon the head tube. Torque=forcexradius (fork length)
hit a bump with a 100mm fork compared to 140mm fork at the same speed, u get the same force. but the torque acting upon the head tube is much higher with the 140mm fork. get what i mean?

i feel u bro
owh i see..well u looking from the point of view where the fork hitting the bump and causing stresses to head tube.
i'm looking loading/force come from rider weight to the frame(center of frame). i believe low center of frame(crank area) receive stress more frequent and much more higher. increasing the travel to 140 will cause rider to lean backward and more stresses at the center tube.
btw what u said is true. what im just said is my theory. dont know true or not
