Traction and Total ResistanceWould you please help me with the following question:
A 90 tonne rear dump truck travels on an 8% grade loose gravel road. Determine the traction and total resistancei. On the way up when the truck is loadedii. On the way up if the truck is empty
For the following conditions:* Rolling resistance factor = 100 kg/tonne* Coefficient of friction = 0.35* Vehicle weight empty = 700 kg/tonne of rated capacity* Gross vehicle weight = dead weight + capacity* Grade resistance factor = 10 kg/tonne* Load distribution = 33 % on front tyres and 67% on rear tyres
Given the following data for a vertical curve of a road; G1=-2.5%, G2=+5.5% and station of PVI=250+50.At station 252+50, the vertical curve must intersect an existing road at elevation 48.48ft. the elevation on the tangent section at station 256+5..
what is the final dissolved oxygen concentration (in mg/L) in the waste lagoon after all of the ammonium (NH4 + ) is converted to nitrate? Recall that 4.57 mg of O 2 is need per mg of ammonium (as N) oxidized during nitirification. After all of the..
