How large is the greatest slope this train can climb?

[cmcd]

Homework Statement

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

Homework 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.
