(a)
Interpretation:
Atom numbers per unit cell should be calculated.
Concept Introduction:
The atomic symbol of beryllium is Be and has the atomic number of 4. The element Beryllium is a very rare one in the universe. At normal room temperature this element becomes brittle and it is steel gray material. The chemical properties of beryllium arelikethat of aluminum. In the nature it does not occurs as free element.
(b)
Interpretation:
Unit cell packing factor should be calculated.

- Draw the Shear Force Diagram and Bending Moment Diagram for the beam shown in Fig.1. The beam is subjected to an UDL of w=65m. L=4.5m L1= 1.8m. Assume the support at C is pinned, and A and B are roller supports.

The channel introduces 10dB of losses and AWGN noise with a power spectral density of 1*10-6 W/Hz. The application requires a bit rate of 4.8 Kbps and BER of less than 10^-6. Estimate the require transmit power.arrow_forward
