Question

A rigid platform is supported by three columns (A, B, & C). Columns A & B are made of steel and have a circular cross section with radius 5 cm. Column C is made of aluminum and also has a radius of 5 cm. The columns were installed at a temperature of -10 degree C. If the temperature rises to 50 degree C, determine the reaction forces at the base of each column, and the angle of the platform given the distributed load as shown. Consider how this places a compatibility constraint on the three columns.

Explanation / Answer

on solving we get last eqn as

91.4 Rc - 19.4 Rb + 9.7 Ra = 2.64 * 10^3
