Document Summary

Phys 101: physics for the life sciences lecture 20: Linear rotation x= , v = , a= . A wheel has an initial angular speed of 3. 40 rad/s. T=4. 62 s: how far does the mass rise of the radius of the wheel is 0. 1 m? d=r =(0. 1)(7. 85)= . In a microcentrifuge, samples of blood are placed in capillary tubes. If we consider a rod on which two forces are acting on in equal and opposite directions then the. Net force will be zero and the centre of mass will not accelerate. The object will have an angular acceleration due to torque acting on the system. When a force is applied to a wheel the torque can be calculated by: Drawing a dashed line along the force vector called the line of action. Then, drawing a line from the origin that intersects the line of action at 90 . This new line is called the lever arm (l)
