SUMMARY

The discussion focuses on determining the friction force acting on a block at a 30-degree angle with a force P of 200 N. The coefficients of friction are given as static (us=0.3) and kinetic (uk=0.2). The calculated friction force is 326.79 N, while the normal force is 966.025 N. The participants emphasize the importance of correctly identifying the direction of acceleration and friction in the free-body diagram to ensure accurate calculations.

PREREQUISITES
  • Understanding of free-body diagrams
  • Knowledge of static and kinetic friction coefficients
  • Ability to perform force summation calculations
  • Familiarity with Newton's laws of motion
NEXT STEPS
  • Review the principles of static and kinetic friction in physics
  • Learn how to accurately draw and analyze free-body diagrams
  • Study the application of Newton's second law in friction problems
  • Explore examples of force summation in inclined plane scenarios
USEFUL FOR

Students studying physics, particularly those focusing on mechanics and friction problems, as well as educators looking for practical examples of force analysis.

Homework Statement


I have attached a picture. Determine the friction force acting on the block shown when the angle is 30 degrees and P=200 N.


Homework Equations


us=0.3 (static friction)
uk=0.2 (kinetic friction)


The Attempt at a Solution



I set up a free-body diagram w/the 1kN, P, Normal force and frictional force. I was able to solve for both the Normal force and frictional force. I got 326.79N for friction and 966.025 for Normal. I thought I was incorrect because it doesn't fit into the f<=usN

Perhaps if you showed your working, we could show you where you've gone wrong...
 
I would draw a better diagram :).

One with acceleration; in which direction is it pointing? Acceleration sets your positives/negatives on the axis on the diagram. The friction; in which way is friction pointing/acting?

After doing such you can do a summination of forces =).
