Weight Stresses

In addition to bending stresses caused by a wind load or a seismic load, the weight of the tower and its contents will produce a cumulative axial compressive stress on the shell which increases with distance X from the top of the tower. In a vessel with uniformly distributed compressive loads from the dead weight, this compressive stress is simply the summation of the total weight of the tower above the plane X divided by the cross-sectional

Single base, multiperforated, MIO gun propellant in bulk was used in the propellant tests. The illuminant material was a 50 50 mix of sodium nitrate and powdered magnesium. The safety approval tests were conducted with a smaller charge weight than that shown, 50 pounds of the illuminant mix. To be complete, the proof test charge of 2.5 pounds is shown. That charge weight stressed the shield structure to its limit and was not increased. 

The direct stress due to the weight of the vessel, its contents, and any attachments. The stress will be tensile (positive) for points below the plane of the vessel supports, and compressive (negative) for points above the supports, see Figure 13.18. The dead-weight stress will normally only be significant, compared to the magnitude of the other stresses, in tall vessels. 

Because the pattern of bone formation occurs in response to weight/stresses borne by the bone, disuse osteoporosis occurs in individuals who are on bed rest for prolonged periods of time, as well as in individuals experiencing the relative weightlessness of space flight.

The formula seems to fit limited observational data reasonably well. This stress is cumulative with the weight, stress and effects of pressure and is alternating in sign as the column vibrates. It also includes the direct wind stress (which is small anyway in this range of wind velocity).

Once the equivalent weighted stress is calculated, the curve run is integrated. The geometrical interpretation of the calculation result is the area beneath the curve. This number bears the meaning of tolerated stress over system usage. After the failure of several systems and applying the above described procedure. 

I.ayout solutions for stress problems due to reciprocating equipment, wind, or earthquake are similar in nature to the solutions provided for weight stress problems. Thus, most solutions revolve around rout-...
