Rather than rotate completely horizontally, a carousel rotates at an angle of 10° from horizontal, with a constant angular velocity of 1.571 RAD/s. A box is placed 1.5 m from the axis of rotation. What’s the minimum coefficient of static friction so the box will not slip?

Answer 1

The maximum force on the box will be on the lower side, centripetal force+gravity.

mw^2 r + mgSin10=mu*mg*cos10

figure mu
