Question

A wire 2m long has mass of 4.8 x 1^-3 kg. The wire is inder atension of 150 N. If the wire is made of steel, for whichyoung's modulus is 2x1011 N/m2 and has crosssectional area 4 x 10-5 m2.  Whatis the speed of the transverse wave in this wire? We only have theinfo given to work with to find the answer. I have figured out thatthe frequency is 62.5 Hz while a node is at each end and anantinode is in the middle. Also I have figured out that the wire isstretched to 3.75 x 10^-5 meters. Please help. A wire 2m long has mass of 4.8 x 1^-3 kg. The wire is inder atension of 150 N.

Explanation / Answer

Speed of transverse wave v = [ T / ] where T = tension = 150 N            = linear density = m/ L            m= mass = 4.8 x 1^-3 kg            L= length = 2 m So, v = 250 m / s
