Unformatted text preview: does not slip on the pulleys, and neglect the mass of the cord. 3. The 100-kg ﬂywheel has a radius of gyration about its center of gravity O of k O = . 225 m. If it rotates counterclockwise with an angular velocity of 1400 rev/min before the brake is applied, determine the time required for the wheel to come to rest when a force of P = 1000 N is applied to the handle. The coeﬃcient of kinetic friction between the belt and the wheel rim is μ k = 0 . 4. (Hint: Recall from the statics text that the relation of the tension in the belt is given by T B = T C e μβ , where β is the angle of contact in radians.) 4. A 2-kg mass of putty D strikes the uniform 10-kg plank ABC with a velocity of 10 m/s. If the putty remains attached to the plank, determine the maximum angle θ of swing before the plank momentarily stops. Neglect the size of the putty. 1 Figure 1: Questions 1 and 2 Figure 2: Question 3 and 4 2...
