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
