The moment of inertia of a solid sphere about its diameter is I. The moment of inertia about a tangent is:
A rod of length 2 m has a linear mass density given by λ(x) = 2x, where x is the distance from one end. The centre of mass of the rod is at a distance from that end:
A uniform disc of mass 5 kg and radius 0.4 m is rotating about its central axis with an angular acceleration of 4 rad/s². What is the torque required to produce this angular acceleration? (Take I = ½MR² for a disc)
A uniform rod of mass M and length L is pivoted at one end and allowed to oscillate in a vertical plane. The equivalent simple pendulum length (length of isochronous simple pendulum) is:
A force of 5 N is applied perpendicular to a wrench of length 0.4 m. The torque produced about the pivot is:
A solid sphere and a solid cylinder of the same mass and radius roll down an inclined plane without slipping. Which of the following is correct?
A solid sphere and a solid cylinder of same mass and radius roll down an inclined plane without slipping. The ratio of their accelerations (a_sphere : a_cylinder) is:
The angular momentum of a rotating body is L = Iω. If I doubles and ω halves, L:
