Compute all parts of given problem:

Problem: The coefficients of linear expansion for some common materials are listed in the table to the right. You would like to design an emergency overheating alarm using one of these materials. In your design, at room temperature (23.0°C), a 7.26 cm long cylinder of the material will sit with one end against a wall and the other just barely touching a button. Once the heat causes the cylinder to lengthen by 0.0258 cm, the button will be activated, turning on the alarm.

Part A: At what temperature will the alarm be triggered if the cylinder is made out of brass?

Part B: At what temperature will the alarm be triggered if the cylinder is made out of glass?

Please give a full detailed explanation of solution.
