الرجاء من كل من لديه معلومات عن الميكانيكا الكلاسيكية مساعدتي في حل هذا السؤال للضرورة القصوى:eh_s (16)
a wheel of mass M . radius of gyration k , spins smoothly on
a fixed horizantal axle of radius a which passes through a hole of slightly larger radius at
the hub of the wheel . the coefficient of friction between the bearing surface is M . if the wheel is initially spinning with angular velocity w0 find the time and the number of turns that it takes to stop
