The structure shown below carries a DL and LL from a machine found on a mine. (a) What specific loads need to be considered when setting up the load combinations? (b) What load case(s) need to be considered to obtain the worst moment (to be designed against) in the structure? and where does this moment occur? (c) What load case(s) need to be considered to obtain the worst deflection(s) in the structure? and where does this deflection occur? L Walkway L/3 wide DLA LL4 DL, LL,
