- The Motion Of A Homogeneous Bar Of Mass M In The Vertical Plane Is Determined Only By Its Weight And The Normal Reaction 1 (58.04 KiB) Viewed 37 times
The motion of a homogeneous bar of mass m in the vertical plane is determined only by its weight and the normal reaction of an absolutely smooth horizontal surface (ignoring air resistance), and the motion starts from a unstable rest position θ=0∘. The length of the bar is equal to L=1.5 m. The angular velocity of the bar in the final position θ=90∘ must be determined. Note: the moment of inertia of the bar in relation to the center of mass of the bar is equal to mL2/12 Select one: 5.43rad/s 2.43rad/s 1.43rad/s 3.43rad/s 4.43rad/s
