Question: A 3 0 5 hp ( power - shift ) dozer is used in a pushing operation. The dozer is equipped with a straight blade.

A 305 hp (power-shift) dozer is used in a pushing operation. The dozer is equipped with a straight blade. The material (dry and non-cohesive) weighs 98 pcf in the bank state. It is estimated the material will swell 6%, from bank to loose state. The center-of masstocenter-of-mass pushing distance is 200 ft. Job efficiency can be assumed to be equivalent to a 45-min hour. The companys normal O&O cost for these machines is $95 per hour and the operators wage is $15.00 per hour plus 40% for fringes, insurance, and workers compensation.
Hint: T4.4 must be used to find either the correct swell % or the
correct swell Factor.
