4 cards from this section. Quick, good the night before a test.
Calculate the rolling resistance for a truck weighing 20 tons with a rolling resistance of 50 kg/ton.
Multiply the weight (in tons) by the rolling resistance.
What is the penetration resistance for a vehicle that sinks 5 cm with 6 kg/ton resistance?
Use the formula: Penetration Resistance = Depth (cm) × Resistance (kg/ton) × Weight (tons).
What is the formula for calculating total rolling resistance?
Think about what we multiply for finding rolling resistance!
True or False: Grade resistance increases as the slope steepness increases.
Grade resistance relates to how steep a slope is.
A construction vehicle has a gross weight of 20 tons, a rolling resistance of 50 kg/ton, and encounters a slope of 5%. Calculate the total resistance faced and determine the usable power if the machine's maximum power is rated at 6000 kg.
Calculate each resistance first before determining usable power.
A truck weighs 12 tons with a rolling resistance of 30 kg/ton and is lowering down a slope of 7%. Calculate the grade resistance and determine how much usable power remains from a maximum power of 7000 kg.
Calculate to understand how resisting forces impact usable work.
