Equation Explanation: The equation given is S = 0.014 t + 0.19, where S is the maximum stress in megapascals and t is the additional mass in metric tonnes.Stress Change with Mass: The term 0.014 t represents the part of the stress that changes with the additional mass on the bridge. For every metric tonne added, the stress increases by 0.014 megapascals.Interpretation of 0.014t: Therefore, the best interpretation of the expression 0.014 t is that it's the portion of maximum stress due to the additional mass alone, which is in megapascals.
