Determine the base width and height of a triangular spoil bank of dry common earth resulted from excavating a trench with cross section of $0\mathrm{.}8**1m$ and length of $100m.$ Note: the length of the spoil bank is similar to the trench.

If a m$$dium shovel with bottom dump bucket $[V=5m]$ used to load the resulted soil in a truck. Determine the time of loading, if the efficiency factor is $0\mathrm{.}95,$ the swing angle is $90,$ and the bucket fill factor is $0\mathrm{.}97.$
