- all the cyclinder are 600mm-diameter and their weights are 800 N each.Sigma A is - 185.9 MPa and Sigma B is -158.42 Mpa. Please explain how.1 Proof that a solid aluminum block of 4 mm x 3 mm x 3 mm, such as shown in FigureQ1 (a), can float on water at 20 °C due to the effect of surface tension. The density ofthe aluminum block is 2700 kg/m3. Determine the contact angle. 2. A solid alloy cylinder having a diameter of 6.48 cm slides downward at a terminalvelocity of V through a vertical pipe. The downward motion is resisted by an oil filmbetween the piston and the pipe wall. Determine the oil viscosity when the velocityV is 5 m/s. The inner diameter of the vertical pipe is 6.5 cm, and the alloy density is3500 kg/m3.
