Question
A 0.50kg cord is stretched between two supports 10m apart. When one support is struck by a hammer, a transverse wage travails down the cord and reaches the other support in 0.85seconds, what is the Tension, unit for Tension in this problem is (Ft), in the cord? A 0.50kg cord is stretched between two supports 10m apart. When one support is struck by a hammer, a transverse wage travails down the cord and reaches the other support in 0.85seconds, what is the Tension, unit for Tension in this problem is (Ft), in the cord?Explanation / Answer
mass per unit length
u = 0.5/10 = 0.05kg/m
from the given data
Velocit = 10/0.85
V = 11.7647 m/sec
we know that velocity
V = sqrt ( T /u)
where T is tension
T = 6.92 N ------------------------- answer
