2016 F = ma Exam — Question 20

A uniform solid right prism whose cross section is an isosceles right triangle with height h and width w = 2h is placed on an incline that has a variable angle with the horizontal θ. What is the minimum coefficient of static friction so that the prism topples before it begins sliding as θ is slowly increased from zero? w h θ — Source: Question 20, 2016 F = ma Exam, © 2016 American Association of Physics Teachers (AAPT) and the U.S. Physics Team.
