    A wood cutting saw is plugged into a source of 100 volt DC power. The current drawn by the machine as it cuts through a log is given by the following relationship: I(t) = 10sin(.31416 t) where t = seconds.
    It takes 10 seconds to cut through the log and the saw is stopped at the end of the cut so that another may be placed into the feed mechanism.

    Please determine the total amount of Joules required to cut through the log.
