A crawler$-$mounted dragline is to be used for the excavation of loose earth and gravel. The dragline is operating at a least favorable angle of $35$ degrees and a boom length of $21m.$ The bucket size used is $\frac{23}{4}$ cubic yards, assuming the bucket fill factor of $90\%.$

Calculate the safe lifting capacity of the THREE types of buckets $($Light Duty, Medium Duty, and Heavy Duty$),$ and determine the acceptability for use?

Show calculation below work sheet, then record answers $($ALL $6)$ in the following question.

the $6$ question are $($what the light duty safe lifiting capacity and is it accetable, same should done for the other two types$)$
