Chegg.com 5 / 5 119% + Question 4 (30 points): An excavator purchased for A TL has a 200 HP diesel engine and bucket size of 2 % cubic yard. Its total life and yearly working time are given as 10 years and 2200 hours, respectively. The excavator will be used in the excavation work of B m' common earth, which is measured as bank volume. The hourly production of the excavator in terms of loose volume (Q) is given as C mcommon earth. Using the given information, answer the following questions: a) (10 pts.) Determine the hourly cost of the excavator according to cost details given below: Unit price of the fuel: 7 TL/kg Unit price of the lubricating oil: 5 TL/kg Salary of the operator: 5,000 TL/month Hourly wage of the helper: 12 TL'hour (Serves for two excavators) Yearly interest rate: 20% b) (5 pts.) Determine how many days does it take to complete the excavation work if the excavator works 10 hours/day, c) (8 pts.) By calculating the correction related to the efficiency of job and management conditions (ke), determine the efficient working minutes in an hour according to the details given below: Average depth of cut: 3.9 meters B Chegg.com 5/5 1195 b) (5 pts.)
