How do you convert 20,000 kg into tons?
Remember the conversion factor: 1000 kg = 1 ton.
If the rolling resistance is 40 kg per ton for 10 tons, what is the total rolling resistance?
Multiply weight in tons by kg per ton.
Which of the following is the calculation for rolling resistance?
Think of the unit conversions first!
True or False: Grade assistance increases the power needed to move down a slope.
Consider how gravity affects movement.
A heavy vehicle has a total weight of 40,000 kg. If the rolling resistance is 30 kg per ton and the vehicle must ascend a 6% slope, calculate the total resistance and usable power if the machine can produce 8000 kg of pull.
Break the problem step by step – first calculate resistances, then find usable power.
A road grader weighs 25 tons and experiences rolling resistance of 50 kg per ton. If it must travel on a 4% incline, calculating total resistance and determining if it can tow a 10-ton load given that the available rimpull is 6000 kg.
Focus on each resistance component methodically for proper answers.
