    Finding minimum force

    They do give mu as .3. I think I might be able to solve the problem now. If I cant Ill post back. thanks for the help.

    Finding minimum force

    That makes sense if the initial movement is vertical. But how could I find the tension if the initial movement is horizontal. Would'nt that bring us back to the 3 variable 2 equation thing? If it would help I could scan the problem from the book also.

    Finding minimum force

    The problem Im having is that in all the figures (in the image) I have 3 variables with only 2 equations. In figure 3 The only way I could solve for the variables would be to set the normal force equal to the weight, however if the tension is also pulling up it would decrease the normal force...
