Consider the member shown left, which is a rectangular cuboid of dimensions 2LX2LXL hanging on a fixed support at 3L. This member has a volumetric mass density p (UNKNOWN), a coefficient of thermal expansion a and a Young's modulus E. The member is subjected to its own weight (note that the effect of weight is not neglected in this problem) and a temperature change AT. The gravity acceleration g is given. Determine the minimum value of the volumetric mass density Pmin at which the structure touches the ground at 0. 3L 24 21 21 fixed support Consider the member shown left, which is a rectangular cuboid of dimensions 2LX2LXL hanging on a fixed support at 3L.
