If the cord attached to the vertical wall in Fig. 8.44 were horizontal (instead of at a angle), what would the tensions in the cords be?
Answer to relevant QuestionsA force is applied to a cord wrapped around a solid 2.0-kg cylinder as shown in Fig. 8.45. Assuming the cylinder rolls without slipping, what is the force of friction acting on the cylinder? For the system of masses shown in Fig. 8.46, find the moment of inertia about (a) The x-axis, (b) The y-axis, and (c) An axis through the origin and perpendicular to the page (z-axis). Neglect the masses of the connecting ...A meterstick pivoted about a horizontal axis through the 0-cm end is held in a horizontal position and let go. (a) What is the initial tangential acceleration of the 100-cm position? Are you surprised by this result? (b) ...A ball with a radius of 15 cm rolls on a level surface, and the translational speed of the center of mass is 0.25 m/s. What is the angular speed about the center of mass if the ball rolls without slipping? A cylindrical hoop, a cylinder, and a sphere of equal radius and mass are released at the same time from the top of an inclined plane. Using the conservation of mechanical energy, show that the sphere always gets to the ...
