Problem 33 to 35 A com is to be stored in a flat storage {flat bottom) having a dimension of 20m x 3m {D x h] that is made of corrugated steel. The coefficient of static of friction is 0.5; the equivalent grain depth is ?m; use material density of 3'21 kg! m3 33. Determine the maximum static vertical pressure [A] 141.3 kPa [C] 49.5 kPa [E] 41.? kPa [D] None of the above 34. Determine the lateral pressure at the bottom most portion of the storage bin. [A] 70.6 kPa [C] 24.8 kPa [B] 20.85 kPa [D] None of the above 35. Determine the lateral pressure at the top most portion of the storage bin. [A] 70.6 kPa [C] 24.8 kPa [B] 20.85 kPa [D] None of the above
