A thin-wall aluminum pop can is subjected to an internal pressure of 100 psi. The diameter and the wall thickness of the can are 2.5 inch and 0.004 inch respectively. The Young’s modulus and Poisson’s ratio for aluminum are

For a gate width of 2 m into the paper, determine the force required to hold the gate abc at its location.

Apiston-cylinder device contains 0.1 m3 of liquid water and 0.9 m3 of water vapor in equilibrium at 800 kpa. heat is transferred at constant pressure until the temperature of water reaches 350 °c. determine (a) the quality of water at the initial state (b) the work associated with this process, (c) the heat associated with this process.

Ahelical coil spring has a mean diameter of 50 mm, a wire diameter of 5.5 mm and is wound with a pitch of 10 mm. the spring steel has an ultimate strength of 1250 mpa. find the force needed to compress the spring solid and the wire stress in this condition. state whether the spring will return to its initial length.
