A laser Doppler vibrometer (LDV) is a science tool used to evaluate a surface's non-contact vibration
Explanation:
laser Doppler vibrometter (LDV) is a science tool used to evaluate a surface's vibration without in contact to the surface. The LDV laser beam is directed to the surface of significance & the wave amplitude, frequency is obtained from the reflected laser beam frequency's Doppler change due to ground movement. it identifies the Doppler effect or shift of laser light reflected from the sample object
Answer:
a)True
Explanation:
Rolling:
Rolling is a metal forming in which a material passes through two or more than two depends on conditions,rolls to produce the desired product.
Ring rolling:
In ring rolling a thick ring compresses by rolls to produce the large diameter ring.Actually volume of material is constant so when diameter of ring increases then to compensate it, the thickness of ring reduces .In simple words we can say that in ring rolling a thick ring of smaller is rolled into a thin ring of larger diameter.
