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.

we can conclude that the melting point of table salt is above room temperature (it's actually 801 deg c). the melting point of mercury must be below room temperature (- 39 deg c).
