QUESTION 1 The 43 kg disk shown in the figure below is pin supported at its center. Determine the number of revolutions it must make to attain an angular velocity of 55 rad/s starting from rest. It is acted upon by a constant force F= 20 N, which is applied to a cord wrapped around its periphery, and a constant couple moment M-10 Nm. Neglect the mass of the cord in the calculation. MONO om
The tangential force F shown in figure below is applied to a disc is allowed to rotate about an axis through its center. The diameter of the disc is 24.0 cm. The magnitude of this tangential force is given in the graph of F vs. Angular Position. With the disc at rest initially and ignoring frictional torque, the disc's angular velocity after one full rotation is -31.4 rad/sec. What is the moment of inertia of the disk? 2.40 × 10-1...
A disk of mass M and radius R is on the horizontal table, and an external force F is applied to the disk as shown in Figure above. The coefficient of friction between the disk and the table is and it is large enough that the disk is rolling without slipping. The initial velocity of the center of mass is V_3 = 0, the initial angular velocity is 0. Find the acceleration of the center of mass of the disk...
The Geneva mechanism shown is used to provide an intermittent rotary motion of disk S. Disk D weighs 2 lb and has a radius of gyration of 0.9 in. and disk S weighs 6 lb and has a radius of gyration of 1.5 in. The motion of the system is controlled by a couple M applied to disk D. A pin Pis attached to disk D and can slide in one of the six equally spaced slots cut in disk...
