A vertical hollow steel tube is 2.5 m long. Its internal diameter is 5 cm and its external diameter is 6 cm. Calculate the increase in length of the tube when a load of 1.5 x 10 kg is suspended from the lower end. For steel Young's modulus is 21 x 1010 N m2 and the shear modulus is 8.3 x 1010 N m-
please answer both questions
Twin 3. (2 pts) The tension force in a wire is 160 N when it is stretched between two fixed points 0.8 meters apart. The mass per unit length of the wire is 2.5 x 10-4 kg/m. A standing wave pattern having 5 antinodes is observed. Find: (a) the wave speed on the string, (b) the wavelength of observed standing wave, and (c) the frequency of the oscillation.
