14600ksi, apr
For the shown structure, AB is made by C83400-red-brass (Ebr
9.8 × 10-6/ °F) and BC is
made by 2014-T6-aluminum (Eal 10600ksi, a al = 12.8 × 10-6/°F). AB and BC are joined at the collar B and
fixed connected at their ends. The cross sectional area of each member is 1.75 in². If there is no load in the
