Determine the power that is required to operate a train of $32$ cars on a level tangent if the total load including is supported by $128$ axles carrying an average of $25$ tons$/$axle with conventional equipment traveling at $95$ mph $.$

$F_{rT}=0\mathrm{.}6+\frac{20}{m}+0\mathrm{.}01u+\frac{k}{nm}{u}^2,Fc=0\mathrm{.}17**(gage)$

Where:

Where:

$F_{rT}=$ rolling resistance force $($lb$/$ton$)$

$m=$ average load per axle in tons

$n=$ number of axles

$nm=$ average weight of locomotive or car in tons

$[$iel lis siply

$k=$ air resistance coefficient: ${0\mathrm{.}07}_{?}$ for conventional equipment; $0\mathrm{.}16$ for

piggyback; $0\mathrm{.}0935$ for containers

$Fc=$ curve resistance on trains $($lb$/$ton per degree of curve$)$ gage $=$ gage of track in ft $.$
