During the process of encapsulation, how does the pc determine if the packet is destined for a host on a remote network? (a) by checking the arp cache for the destination host mac address (b) by querying the dns server for the information of the destination host (c) by sending a broadcast to the local lan segment to see if there is any response (d) by performing the and operation on the destination ip address and its own subnet mask

Explanation:

Cross sectional area of post  = 3.14 x(10.5)² x 10⁻⁴ = 346.18 x 10⁻⁴ m²

Weight = mg = 8300 x 9.8 = 8.134 x 10⁴ N

Stress = weight / area

= 8.134 x 10⁴ / (346.18 x 10⁻⁴)

23.49 x 10⁵ N / m²

Strain = stress / modulus of elasticity of steel

modulus of elasticity = 190 x 10⁹ Pa

strain =  Stress \ young modulus

=

= 12.36 x 10⁻⁶

strain = change in length / original length

change in length = original length x strain

= 2.7 x 12.36 x 10⁻⁶

= 33.372 x 10⁻³ mm

.033 mm.
