Bоth rоds BD аnd CE hаve the sаme crоss section area 10-4 m2. They are also made of the same material with Young's modulus 200 GPa and coefficient of thermal expansion (1+x) × 10 -4/oC. Bar ABC is rigid. The structure is assembled at 20 oC. BD experiences a temperature increase while the temperature of CE remains the same. If the strain in CE rod should not exceed 0.004, what is the maximum temperature of BD can be increased to? AB = BC = BD = 1 m, CE = 2m. Please enter your calculated temperature in the box below.
