A solid square bar of cross-sectional dimensions CS1 x CS1 is attached rigidly to the wall at point A and has a gap of 1 mm from the rigid wall at point B at T degree C. Knowing the bar is made of aluminum,
L =
L m
\delta=
gap m
T_n=
nT degree C
E=
E Pa
\alpha=
a
\delta = \alpha \Delta T L
round((gap / (a*L) + T)*1000) / 1000 The correct answer expected from the student
round((a * (nT-T) * L)*1000) / 1000 The correct answer expected from the student
round((gap / (L * (nT-T)))*1000) / 1000 The correct answer expected from the student
round((gap / (a * (nT-T)))*1000) / 1000 The correct answer expected from the student
