A bar, 1 cm 2 × 200 cm and mass 2 kg, is clamped at its center. When vibrating longitudinally it emits its fundamental tone in unison with a tuning fork making 1000 vibrations/s. How much will the bar be elongated if, when clamped at one end, a stretching force of 980N is applied at the other end? Somebody please answer this quickly. Ive been trying to solve since afternoon.
