Load Case 1: Lifting The loaded cask is lifted using the two upper trunnions as shown in Figure 1. Load Case 2: Handling The cask is designed to be supported on the two pairs of the trunnions during the transportation. The trunnions also help the cask down-ended and lowered unto the supporting structure. Mastering with waves plugins pdf.

The equation seems appropriate. My concern is the coding in the excell spreadsheet in which leaving out the parenthesis makes a significant difference.
Without the parenthesis in the denominator the numerator is only divided by 'W' and not '(W*(t^2/6)).
The author may have multiplied t instead of squared t as well.
In the denominator of the last equation it has '(W*(t2/6)'..
Is that t^2 or t*2?
Also in the excell equation is leaves out a set of parenthesis.
These two possible errors results in dramatic changes in the equation.
