4 cards from this section. Quick, good the night before a test.
What is the rolling resistance for a machine weighing 30 tons with a resistance of 20 kg/ton?
Calculate by multiplying the weight in tons by the resistance value.
If a machine sinks 5 cm into the surface with a resistance of 4 kg/ton, what is the penetration resistance for 10 tons?
Use the formula: Penetration Resistance = Depth in cm * Resistance kg/ton * Weight in tons.
What is the required tractive effort on a 5% slope for a 20-ton vehicle?
Think about the 10 kg per ton guideline for grade resistance.
True or False: Grade assistance means additional effort is needed for downward movement.
Consider how gravity affects movement in logistical calculations.
A bulldozer weighing 25 tons has a rolling resistance of 80 kg per ton. It's asked to move a load up a 10% slope. Calculate the total resistance.
Add rolling and grade resistance to find total.
A 15-ton excavator has a maximum rimpull of 6000 kg. It faces a rolling resistance of 50 kg/ton. Calculate available pull at a 3% slope.
Understand how resistance impacts the rimpull available.
