Viscous
Coulomb
None of these​

Answer 1

Answer:

Coulomb

Explanation:

Answer 2

Given:

When a vibrating system slides on a dry surface.

To Find:

the damping is  

a. Solid

b. Viscous

c. Coulomb

d. None of these​

Solution:

The answer is the coulomb damping.

Coulomb Damping:

• It arises when bodies slide on a dry surface.
• To start the motion, there must be a force acting upon the body that overcomes the resistance or the oppose caused by friction.
