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.
💡 Hint: 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.
💡 Hint: Focus on each resistance component methodically for proper answers.
