The time required to complete the filling and emptying cycle for a refuse collection vehicle.
Answer to Problem 3.1P
The time required to complete the filling and emptying cycle for a refuse collection vehicle is
Explanation of Solution
Given:
The two container of
The refuse is picked up twice per week.
The truck has a compaction ratio of
The pickup time is
The time spend by truck on disposal is
The time spend to reach the disposal site is
Calculation:
Assume the volume of the truck as
Calculate the volume of refuse produced by each resident in
Here, the volume of refuses produces by each resident is
Write the expression to calculate the compacted volume by the truck’s compacting ratio.
Here, the compacted volume is
Substitute
Write the expression to calculate the number of loads done by the truck.
Here, the number of loads done by the truck is
Substitute
Write the expression to calculate the total time of cycle.
Here, the total time of cycle is
Substitute
Conclusion:
Thus, the time required to complete the filling and emptying cycle for a refuse collection vehicle is

- 2. Find the equivalent concentrated load(s) for the bags of cement stacked on the dock as shown here. Each bag weighs 100 lbs and is 12 inches long. Draw the loading conditions for each showing the equivalent concentrated load(s). 1 bag = 100lbs L= 12 ft L= 6 ft L= 8ftarrow_forwardI have a question for this problem in the first one wouldn't it be finding the total weight of the bags which =4800lbs and the multiply that by 12ft to find the concentrated load?? but if this is the case the load would end up as lbs/ft so I'm not too sure that is right.arrow_forwardThere are 2 parts A) L=12ft B) L1= 6ft, L2= 8ftarrow_forward
