electric power plant orbiting in the Geostationary Earth Orbit (GEO). It consists of mainly three segments; solar energy collector to convert the solar energy into DC (direct current) electricity‚ DC-to-microwave converter‚ and large antenna array to beam down the microwave power to the ground. The first solar collector can be

transparent or opaque solids‚ such as polished glass‚ or gases. Principles A spectrophotometer is employed to measure the amount of light that a sample absorbs. The instrument operates by passing a beam of light through a sample and measuring the intensity of light reaching a detector. Classes a.) Single Beam Spectrophotometer Light from the source lamp is passed through a monochromator‚ which diffracts the light into a "rainbow" of wavelengths and outputs narrow bandwidths of this diffracted spectrum

POT TENDING MACHINE PTM is the crucial equipment of large anode pre-baking workshop. It is used in the environment of high temperature‚ large current‚ strong magnetic field and HF gas. It can perform the following procedures ANODE CHANGE: Anode in the pots is changed at an interval of every 27 days since daily 1.5 cm of the anode gets consumed. A carbon block is usually 55 cm high of which only 40 cm can be used up. The main reason behind the anode consumption is the following electrolytic

In an experiment‚ a 500-pound weight is placed in the center of the beam‚ and the stress in the beam is measured to be 1‚000 psi. If the stresses in the beam continue to increase at the same rate with added weight‚ how much additional weight can be added to the same location on the beam before the beam will break? 500 pounds 1‚000 pounds 1‚500 pounds 3

Check to make sure that the centigram beam indicator aligns with the arrow on the stand. If zero‚ place object in the center of the platform and move beam weights until the beam indicator realigns with the arrow. Record the weight measurement.

Engineering Economics HW2 – 23/10/2012 Q 3.3 Amalgamated Iron and Steel purchased a new machine for ram cambering large I-beams. The company expects to bend 80 beams at $2000 per beam in each of the first 3 years‚ after which the company expects to bend 100 beams per year at $2500 per beam through year 8. If the company’s minimum attractive rate of return is 18% per year‚ what is the present worth of the expected income? P = 80(2000)(P/A‚18%‚3) + 100(2500)(P/A‚18%‚5)(P/F‚18%‚3) = 160‚000(2
