In this problem, we have a uniform rod of mass m and length l, horizontally hinged in a vertical plane. This rod is released, so we have to find the angular acceleration, angular velocity, linear acceleration, and hinge force. 10:59 - 20:44 RBD Problem 2: Based on the torque and angular acceleration relation. In this problem, we have a uniform rod of mass m and length l, horizontally hinged in a vertical plane. This rod is released, so we have to find the angular acceleration, angular velocity, linear acceleration, and hinge force when the rod becomes vertical. 20:44 - 31:09 RBD Problem 3: Based on the torque and angular acceleration relation. In this problem, we have a uniform rod of mass m and length l, at some angle on a enough rough surface. This rod is released, so we have to find the angular acceleration, angular velocity, linear acceleration, normal force and hinge force just after the release. 31:09 - 59:20 RBD Problem 4: Based on the torque and angular acceleration relation. In this problem, we have a uniform rod of mass m and length l, horizontal to the plane. This rod is released, so we have to find the angular acceleration, angular velocity, linear acceleration, normal force, and hinge force when the angular displacement of the rod is 53 degrees. With the help of this problem, ABJ Sir explains each and every basic concept of rigid body dynamics and clarifies the concept using the problem. 59:29 - 01:08:41 RBD Problem 5: Based on the torque and angular acceleration relation. In this problem, we have a Horizontal rough table of mass m and radius R and friction coefficient mu. The initial angular velocity of the table is given to us. So we have to find the angular acceleration of the disc, also find time taken and no of rotation completes of the disc before its stop. 01:08:41 - 01:17:48 RBD Problem 6: Based on the torque and angular acceleration relation. In this problem, we have a uniform square plate of mass m and length, and one corner of the plate is hinged. This plate is released as given diagram, so we have to find the angular acceleration, angular velocity, linear acceleration of COM, and hinge force just after the release. Also find the maximum angular velocity and hinged force at that instant. 01:17:48 - 01:25:50 RBD Problem 7: Based on the torque and angular acceleration relation. In this problem, we have a uniform square plate of mass m and length, and one corner of the plate is hinged. This plate is released as given diagram, so we have to find the maximum angular velocity and hinged force at that instant.
