1- For a mass spring system, if the free length of the spring is
9cm and is elongated by 4 cm under the influence of the mass, the
the natural frequency of the system is?
2- In journal bearings, the lubrication type when surface
contact is continuous and continuously renewed adsorbed surface
film that reduces friction and wear is called?
3-Is caused when the metal is unable to fill the mold caving
completely and this leaves unfilled pockets?
