Cylinder volume - Clearance volume.

Cylinder volume × Clearance volume.

Cylinder volume ÷ Clearance volume.

Solution:

Which of the following relations is true for viscous damping?

None of the above

Force is proportional to relative displacement

Solution:

What is the effect of damping on the phase angle at the resonance frequency?

Phase angle increases as damping increases

Phase angle increases as damping decreases

Phase angle decreases as damping increases

Damping has no effect on phase angle
