A tractor is fitted with a hole-drilling attachment. The tractor has weight WV = 2000 lb, the operator has weight WO = 180 lb, and the supplemental weights at the front of the tractor weigh WE = 300 lb.
(a) Determine the largest thrust that may be produced by the drilling attachment at point A.
(b) Describe some simple ways the drilling thrust determined in Part (a) can be increased (e.g., addition of more weight at E, removal of weight at E, repositioning of weight from E to D, and so on).
