Please click and read, "How Social Media is Having a Positive Impact on our Culture." In a paragraph on page 2, it says, "Social media simultaneously draws us nearer and distances us." Explain what he means in a short essay.*paragraph 2 How Social Media Is Having a Positive Impact on Our Culture Communicate with each other when we're apart. Describe a piece of bacon, and hang on every word. Is it better than a conversation with "real words?" No. But is it better than waiting two more days, when the mundane moment that I long to hear about so much is gone? Yes. I guess one man's TMI is another man's treasure. Moments later, I sat down and opened the paper. A headline immediately stood out: In China, microblogs finding abducted kids with the subhead, "A 6-year-old who was snatched when he was 3 is discovered with a family 800 miles away." Apparently, the occurrence of reclaimed children through the use of China's version of Twitter - and other online forums - has become triumphant news over there. I'm reading about the father's tears, the boy's own confusing set of emotions, the rapt attention of the town and country, and I'm again marveling at the human side of the Internet.

7. An aluminium bracket rod is subjected to a static load F = 3500 N (see figure below). Given aluminium has yield strength of 324 MPa. The rod length $l$ = 150 mm, the rod diameter $d$ = 40 mm and arm $a$ = 200 mm. Calculate at point A: a) The bending stress b) The torsional shear stress c) The maximum shear stress $\tau_{max}$ d) The safety factor $f_s$ based on the maximum-shear-stress theory $f_s = \frac{0.5 \sigma_{yield}}{\tau_{max}}$ [3 + 3 + 2 + 2 marks]

2. The wing on an aircraft is subjected to a drag $F_D$ created by airflow over its surface. It is anticipated that this force is a function of density $\rho$ and viscosity $\mu$ of the air, the length (characteristic) $l$ of the wing, and the velocity $V$ of the flow. Use FLT system to develop a set of dimensionless parameters that can be used to investigate this problem. [20 points]
