Traction and Total Resistance
Would 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 resistance
i. On the way up when the truck is loaded
ii. 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
