Uma indústria de confecção de placas de alumínio deseja transportar 100 placas de alumínio para um cliente. considerando que o veículo de transporte pode carregar até 3 toneladas e que a dimensão de cada placa são 2 m x 50 cm x 2cm calcule,

Questions:

The questions or computes to do are:

a- a massa, em kg, de cada placa de alumínio;

b- a quantidade mínima de viagens necessárias para que apenas um veículo de transporte entregue o material solicitado ao cliente.

Dado: densidade do alumínio = 2,7 g/cm3

a) mass in kg of every aluminum plate

Dimensions of every aluminum plate:
2 M X 50 Cm X 2cm

Volume: 200 cm * 50 cm * 2 cm = 20,000 cm^3

Mass:

density = mass / volume => mass = density * volume = 2.7 g/cm^3 * 20,000 cm^3 = 54,000 g = 54 kg.

the mass of everyplate of aluminum is 54 kg.

b) number of travels required for one truck deliver all the material:

number of travels = amount requested / amount that a truck can deliver in one travel.

amount requested: 100 plates

mass of 100 plates = 100 plates * 54 kg / plate = 5,400 kg

limit of transport per travel: 3 tons = 3,000 kg

number of travels = 5,400 kg / 3,000 kg/travel = 1.8 travels => 2 travels.

at least 2 travels.

Atomicity occurs to prevent updates of the database occurring only partially, which can cause greater problems than rejecting the whole series outright.some are monatomic, diatomic, triatomic etc because it shows the number of atoms. for example, monatomic means it contains only one atom.

D. most models represent a real world object in a simpler way
