A Friction Problem

  1. Mar 12, 2006 #1
    Hi, I got stuck on this and need help...

    So, the given info are:
    theta = 10 degrees
    force, applied = -2.00 x 10^4 N
    and mew k = 0.797
    gravity = 9.81 m/s^2

    Is that right? Now this is where I'm stuck.. I'm not sure what I need to find first and the equations to use to find it...

    Please help... thank you!

    Draw an free body diagram remembering the fact that the normal force will be applied normal to the surface. Have you solved any sliding questions before using friction?

    Yes, I've drawn a free body diagram, but I'm not sure how to solve it now.

    I have not solved questions using friction before.

    Do I need to find the x and y components and go from there?

    Yes, you need to resolve components so that they are all either parallel or perpendicular to the inclined plane.

    Alright, I've gotten it. Thank you, everyone.
