Engineering optimzation·damping-force-calculation

Damping Force Calculation

Given a damper with viscous coefficient and a velocity, calculate the magnitude of the damping force dissipated by the damper. The damping force is proportional to velocity with a negative sign indicating opposition to motion.

✓ All 3 test cases pass.

Inputs

Viscous damping coefficient

Damping coefficient in units of Ns/m or Nms/rad

Velocity or angular velocity

Linear velocity (m/s) or angular velocity (rad/s)
