hard problem 27(Find the required angle)

  • A uniform solid cylinder is placed with its axis horizontal on a plane, whose inclination to the horizon is α. Show that the least coefficient of the friction between it and the plane, so that it may roll and not slide, is 1/3 tanα. If the cylinder be hollow and of small thickness, the least value is 1/2 tanα.
    Solution: In this figure 1 ,  a uniform solid cylinder is placed horizontally on the plane BOCD Which makes an angle α with the hor...
