Homework Help: Time Period of a Pendulum

  1. Apr 2, 2009 #1
    1. The problem statement, all variables and given/known data

    A simple pendulum uses a steel wire as the string. The length of this wire is 1.4 m at room temperature. If the temperature is increased by 11.9 degrees C, the length of the wire increases by 1.69 mm . What is the change in period of the pendulum?

    2. Relevant equations


    3. The attempt at a solution

    g=9.8 m/s2



    =2.376253765-2.374820823=.0014329416 s

    This is wrong :(. What am I doing wrong?

    Check the units on your "relevant equation." I think you will find a problem there.
