The A-36 steel band is 2 in. wide and is secured around the smooth rigid cylinder. If the bolts are tightened so that the tension in them is 400 lb, determine the normal stress in the band, the pressure exerted on the cylinder, and the distance half the band stretches.

Explanation:

(1) first part of solution: we know stress= Force/Area ; Force= 400lb and Area as given

(2) Second part of the solution its the standard formula for Hoop stress and the formula explains all the terms

(3) Third part of the solution we know Strain= (Change in length)/original length  and also the strain are substituted in terms of strain and youngs modulus

Further explanation are given in the attach document.

where are the choice options?

answer: atomic mass was originally used to arrange elements on the periodic table, but is no longer used to organize the modern version.

explanation:

originally atomic mass was used to arrange elements on the periodic table from left to right in a row. each column then shows similar properties of elements of a group.

in modern periodic table, the atoms are arranged in increasing atomic number. as atomic number represents the number of protons in an atom which is unique for every atom.
