Question: Rework Problem including the damping and the external moment M.
Problem: a. In Figure, two disks of equal mass m and radius R are joined by spring of stiffness k2 and roll without slipping on a horizontal plane.
b. Disk A is attached to ground by spring k1, and disk B is attached to ground by spring k3 and a viscous damper with damping coefficient
c. Derive the equation of motion, neglecting the damping due to c and the external moment M.
Identify at least two of the literary elements in the short story that contribute to the theme (e.g., plot, point of view, tone, setting, character, symbolism, etc.), providing an example of each element.
What is the equation for calculating the torque of a motor?
The stiffness of each spring is 30kNim and the initial resisting force in each spring before impact is 4.5kN. Using an energy method calculate the maximum compression of the springs.
