Homework Help: How large is the greatest slope this train can climb?

  1. Apr 9, 2014 #1
    1. The problem statement, all variables and given/known data

    A train wheel's have a coefficient of 0.08. What is the steepest slope the train can climb?

    2. Relevant equations

    Friction force = coefficient x component of train's weight perpendicular to slope x 9.81

    If the train is on the point of slipping
    Friction force = component of train's weight parallel to slope x 9.81

    3. The attempt at a solution[/

    90 - ArcTan ( 1 / 0.08 ) = 4.57 degrees.

    The answer is supposed to be 2.54 degrees ?

    I get the same result you have.
    Perhaps you should check the question and make sure the 2.54 is the answer that goes with that question.
