Answer 2

Answer:

Machines are oiled from time to time because it help to reduce friction so due to this less energy used by machines and the life span of machine also increases and when the solid parts come into sudden contact, the impact may break or fracture the parts. The oil absorbs much of the impact slowing the momentum at the point of contact.
