3 cards from this section. Quick, good the night before a test.
Convert 40,000 kg into tons.
Remember to divide by 1,000.
Calculate the rolling resistance for a vehicle weighing 20 tons with a rolling resistance of 30 kg/ton.
Multiply the weight by the rolling resistance.
What is the formula for calculating rolling resistance?
Think about how weight changes in terms of tonnage.
True or False: Grade resistance increases as the slope of a hill increases.
Consider how gravity affects your movement uphill.
A tractor with a gross weight of 20 tons faces a rolling resistance of 50 kg/ton and climbs a 3% slope. Calculate the total tractive effort required.
Remember to calculate each resistance component and sum them.
If a vehicle weighs 10 tons and sinks 7 cm into the surface with a rolling resistance of 70 kg/ton, is the total resistance more than 1300 kg?
Breaking down into smaller components will help clarify the total!
