A vertical cylindrical tank is 2 m. in diameter and 3.5 m. high. Its sides are held in position by means of two steel hoops, one at the top and the other at the bottom. The tank is filled with water up to 3 m. determine the tensile stress in each hoop.

SECTION: 500mm 20 KN I5 KNIM 1000 mm 12 m Ps 800 KN e : 400 mm (ASSUME IS % LOS SES) A. Determine the stress at the bottom in the free end. (MPa) B. Determine the stress at the top in the fixed end. (MPa)

Aluminum is a poor material to reinforce concrete with, especially as opposed to steel.  There are five primary reasons why; Cost, strength, and stiffness are the first three.  Please name the fourth and fifth reasons and then please explain in detail what would occur if these two were done.

1.) A STEEL WIRE 30 ft LONG HANGING VERTICALLY SUPPORTS A LOAD OF 500 lb. 30 ft NEGLECTING THE WEIGHT OF THE WIRE, DTERMINE THE REQURIED 500 Ib DIAMATER IF THE STRESS IS NOT TO EXCEED 20 ksi AND THE TOTAL ELONGATION IS NOT TO EXCEED 0.20 in. ASSUME E = 29 x 106 psi.
