1. Two particles that have the same mass m = 0.5 kg are connected by a rotation aixs massless cord of l = 20.0 cm and rotate around O with angular speed w = 10.0 rad/s initially, as shown in figure (a). Two seconds later, two particles are mo moved toward the rotations axis, reducing their separation to l' = 15 cm, as shown in figure (b). What is the angular velocity at time t = 2 s? (hint: L...
5. A half section of a uniform thin pipe of mass m 2 kg is at rest when a force P 40 N is applied at point A as shown. The static and kinetic friction coefficients are μ': 0.15 and μ"01, respectively. Determine (a) the angular acceleration, and (b) the magnitude and direction of the friction force between the thin pipe and the horizontal plane. The distance between the geometric center O and mass center G of the thin pipe...
A meterstick (L-1 m) has a mass of m-0.17 kg. Initially it hangs from two short strings: one at the 25 cm mark and one at the 75 cm mark. "What is the tension in the left string? Net You currently have submissions for this question. Only 10 submission are allowed. You can make 10 more submissions for this question. 2. Now the right string is cut! What is the initial angular acceleration of the meterstick about its pivot point?...
17. [1pt) A wheel of mass m = 1.87 kg and moment of inertia, I = 1.530 kg.m- is supported by a pivot a distance d=0.17 m from the wheel, as shown in the diagram. The axle through the wheel is initially in the horizontal plane, as shown, and the wheel is spinning about the axis in the sense indicated, with an angular velocity o = 90 rad's. Answer the following three questions using the choices given; c.g., if the...
