Unformatted text preview: Problem 9.19 Each box weighs [0 lb. The coefficient of static friction between box A and box 8 is 0.24, and the coefficient of static friction between box B and the inclined surface is 0.3. What is the largest angle a for which box B will not slip? Strategy: Draw individual freeibody diagrams of the two boxes and write their equilibrium equations assuming that slip of box B is impending. Solution: We have 6 unknowns. 4 equilibrium equations and 2 IO") friction equations ZFA/IT— I0lbsinafif2=0 ZFA\:N2—]01bcosa=0 Era/:foI a lOlbsina=0 ZFB'\:NE —N2-101bC050t=0 f1=0.3Ni. f2 2$0.24ng Solving we find ...

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
