SUMMARY

The maximum slope a train can climb, given a wheel coefficient of friction of 0.08, is calculated using the formula for friction force. The derived angle of 4.57 degrees indicates the steepest slope before slipping occurs. However, the expected answer is 2.54 degrees, suggesting a potential discrepancy in the problem statement or parameters. Verification of the question details is essential for accurate resolution.

PREREQUISITES
  • Understanding of basic physics concepts, specifically friction and forces.
  • Familiarity with trigonometric functions, particularly ArcTan.
  • Knowledge of the relationship between weight components and slope angles.
  • Ability to apply Newton's laws in practical scenarios involving inclined planes.
NEXT STEPS
  • Review the principles of friction in physics, focusing on coefficients of friction.
  • Study the application of trigonometric functions in real-world physics problems.
  • Explore the derivation of forces acting on objects on inclined planes.
  • Investigate common errors in physics problem statements and how to identify them.
USEFUL FOR

Students studying physics, educators teaching mechanics, and anyone involved in engineering applications related to friction and slope calculations.

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.
