Test: Engineering Equipments - 2 - Question 1

### For cleaning and grubbing of construction site of 15000 m2 area, a bulldozer is used which has effective width of 2 m of the blade and an average speed of 2.5 kmph. If hiring charges of bulldozer are Rs. 500/hr., then cost per m2 is

Detailed Solution for Test: Engineering Equipments - 2 - Question 1

Area = 15000 m2
Bulldozer moves 2500 m in 1 hr.
∴ Area cleaned in 1 hr

### Which one of the following statements is correct?

Detailed Solution for Test: Engineering Equipments - 2 - Question 3

Grade resistance does not depends on the type of equipment or the condition or type of road.

Test: Engineering Equipments - 2 - Question 4

The number of trips of a dumper per hour is given by

Detailed Solution for Test: Engineering Equipments - 2 - Question 4

Productive capacity of a hauling unit

Where payload is the maximum recommended load for a hauling unit as prescribed by the manufacturer. Cycle time = Loading time + hauling time + dumping and turning time + return time + spotting and waiting time.

Test: Engineering Equipments - 2 - Question 5

Consider the following statements:
1. The ideal output of a power shovel is achieved at 90° angle of swing.
2. Output from a power shovel is independent of size of trucks.
3. The optimum depth of cut of a power shovel is the one at which the dipper comes out with full load.
4. The optimum depth of cut does not vary with the size of the dipper of a power shovel.

Which of the statements given above are correct?

Detailed Solution for Test: Engineering Equipments - 2 - Question 5

The output of a power shovel depends on,
(i) class of material
(ii) depth of cut
(iii) angle of swing
(iv) job conditions
(v) management conditions
(vi) size of hauling units like trucks
(vii) skill of operator
(viii) physical condition of the shovel
The optimum depth of cut is that depth at which the output is greatest and dipper comes up with full load without excessive downward pressure and tension. This depth varies with the type of soil and size of the dipper.
Ideal production of a shovel is based on operating at 90° angle of swing.

Test: Engineering Equipments - 2 - Question 6

Consider the following statements:
When acquiring a crane for a project work, the important aspects of the specifications will include information on
1. length of hoist line
2. length of boom line
3. tipping condition
4. bucket size
5. angle of swing in absolute terms
6. haul distance

Which of the statements given above are correct?

Test: Engineering Equipments - 2 - Question 7

Which of the following are taken into consideration in determining ultimate operating factor of a typical earthmoving equipment?

Detailed Solution for Test: Engineering Equipments - 2 - Question 7

Operating factor = Engine factor x Time factor Engine factor accounts for operating at rated H.P. during maximum output and below rate H.P. for balance of cycle time.
Time factor accounts for shut down time proportion.

Test: Engineering Equipments - 2 - Question 8

A scraper of self weight 27 tonnes works on sandy clay soil weighing 1800 kg/m3 of bank measure. Haul road rolling resistance is 3.5% and grade is 2% adverse for loaded unit. The earth carried per trip is 14m3 (b.m.). What rim pull, in newton (approximately) is required when travelling loaded and empty, respectively?

Detailed Solution for Test: Engineering Equipments - 2 - Question 8

When loaded the grade resistance will be 5.5% and when empty the grade resistance will be 1.5%.
Total resistance = roiling resistance + grade resistance.

When travelling empty the weight = 27t
Thus rimpull

Test: Engineering Equipments - 2 - Question 9

Two centrifugal pumps work in parallel at a common delivery head of 18m. The first pump delivers 90 /ps at an efficiency of 60% and the second pump delivers 60 /ps at an efficiency of 50%. What is the overall efficiency of the system?

Detailed Solution for Test: Engineering Equipments - 2 - Question 9

Total discharge delivered = 90 + 60 = 150 LPS at delivery head of 18m.
The pumps work in parallel,

Test: Engineering Equipments - 2 - Question 10

Match List-I (Earth Excavating Equipment) with List-II (Uses) and select the correct answer using the codes given below the lists:
List-l
A. Power shovel
B. Hoe
C. Clamshell
D. Bulldozer

List-II
1. Excavation of earth in confined area or pit
2. Rehauling of loose or excavated material from one place to another place
3. Clearing and scrubbing of worksite
4. Excavation of trenches

Detailed Solution for Test: Engineering Equipments - 2 - Question 10

Power Shovel is used in excavation of earth in confined area or pit.
Hoe is used in excavation of trenches because trenches need precise control of dimensions and Hoe is suitable for this purpose.
Clamshell is used in rehauling of loose or excavated material.
Bulldozer is used in clearing and scrubbing of worksite.
