Detailed Solution for Mock Test: SSC JE (ME)- 7 - Question 4

Diesel is in principle easier to refine than gasoline, however it contains more pollutants that must be extracted before it can reach the same levels of emissions as petrol. Per litre, diesel contains more energy than petrol and the vehicle’s engine combustion process is more efficient, adding up to higher fuel efficiency and lower CO2 emissions when using diesel.

Mock Test: SSC JE (ME)- 7 - Question 17

A tapering bar (diameters of end sections being d1 and d2) and a bar of uniform cross section 'd' have the same length and are subjected the same axial pull. Both the bars will have the same extension if 'd' is equal to

Detailed Solution for Mock Test: SSC JE (ME)- 7 - Question 17

E = Stress / Strain = WL / ΔL A
For a tapering rod,
A = π d1 d2 / 4
ΔL = 4WL / π d1 d2 E
For a uniform cross section with diameter d,
A = π d2 / 4
 ΔL = 4WL / π d2 E

The bars have the same length l and are subjected to the same axial pull W. Then for the same extension ΔL
4WL / π d1 d2 E = 4WL / π d2 E
1/ d1d2 = 1/ d2
so d =
