Assuming that the bridge segments are free to pivot at each intersection point, what is the tension t in the horizontal segment directly above the point where the object is attached? if you find that the horizontal segment directly above the point where the object is attached is being stretched, indicate this with a positive value for t. if the segment is being compressed, indicate this with a negative value for t. the answer should be in terms of m (mass) and g (gravity).

Asheet of steel 1.5 mm thick has nitrogen atmospheres on both sides at 1200oc and is permitted to achieve a steady-state diffusion condition. the diffusion coefficient for nitrogen in steel at this temperature is 6 x 10- 11 m2 /s, and the diffusion flux is found to be 1.2 x 10-7 kg/m2 -s. also, it is known that the concentration of nitrogen in the steel at the high-pressure surface is 4 kg/m3 . how far into the sheet from this high-pressure side will the concentration be 2.0 kg/m3 ? assume a linear concentration profile.
