Explanation:
umm can you explain me what i have to answer
Hauling Vehicles that include a semitrailer manufactured prior to or in the model year of 2024, and registered in Illinois prior to January 1, 2025, having 5 axles with a distance of 42 feet or less between extreme axles, may not exceed the following maximum weights: 20,000 pounds on a single axle; 34,000 pounds
True
Explanation:
three point bending is better than tensile for evaluating the strength of ceramics. it is got a positive benefit to tensile for evaluating the strength of ceramics.
Answer:
mechanical efficiency = 54%
Explanation:
given data
power We = 44 kW
density = 860 kg/m³
rate of flow = 0.07 m³/s
inlet diameter d1 = 8 cm
outlet diameter d2 = 12 cm
pressure = 500 kPa
efficiency η = 90%
to find out
mechanical efficiency
solution
we get here shaft power is here
shaft power = efficiency × electric power
shaft power = 0.9 × 44 = 39.6
and
now we get DEmech that is
DE(mech)= m g h + (v² - u ²) .....................1
that is we can write as
DEmech = ρVgh +
= VDP + ×
Plugging in values we now have DEmech that is
DEmech = (0.07m^3/s × 500kPa) +
solve we get
DEmech = 21342 W
DEmech = 21.3 kW
mechanical efficiency is
mechanical efficiency =
mechanical efficiency = 0.54
mechanical efficiency = 54%
