Physics Properties Of Matter Level: High School


A 2.6 m long cylindrical steel wire with a cross-sectional diameter of 5.5 mm is placed over a frictionless pulley , with one end of the wire connected to a mass 6.5 kg and the other end to a mass 3.5 kg .

The acceleration of gravity is 9.8 m/s^2 . Given : Young’s modulus for steel Y = 2 x 10^11 Pa .

What is the tension in the wire while the masses are in motion ? Answer in units of N .
