Find the mass moment of inertia of the thin ring.

Question

A stepped bar with circular cross-section and supported at top, hangs vertically under its own weight. Dimensions of the bar are shown in the figure below. Calculate the elongation of the bar under its own weight. What is the change in diameter of the bar at section AA shown in the figure ? E= 2 x 10 N/mm2, density y = 8 x 10-5 N/mm² and Poisson's ratio m = 0.2. A 100 mm 70 mm -A + + 500 mm 500 mm 1000 mm

Contrary to what you might expect, a solid metal ball can float on water due to the surface tension effect. Determine the maximum diameter of a ball made of material A that would float on water at 20°C with Os=0.0745 N/m. What would your answer be for material B? Use the densities of materials A and B from the following table. 1 Material A Aluminum, density 2600 kg/m³ Material B Silver, density 10500 kg/m³

5.) The figure shows a metal hanging by a thin wire from a floating wood block. The wood block has a specific gravity Sb =0.25, a square base of 80 mm x 80 mm and height of 15 mm. The metal has a volume of 8000 mm^3. Using a unit weight of water 9800 N/m^3 and g=9.80 m/s^2., find the mass of metal in grams. Write your answer in two decimal places. fluid mechanics
