Member AB spans two supports that are a=2.6m apart. It is subjected to a distributed load of w=1000N/m and a concentrated moment of M=830 N*m as shown. The member will have a square 27mmx27mm hole in its cross section oriented at a 45 degree angle as shown. If the material that conposes the member must not be stressed above 190 MPa find the minimum allowable outer diameter of the member b

solve it 1. A group of \( N \) stations share a \( 56-\mathrm{kbps} \) pure ALOHA channel. Each station outputs a 1000-bit frame on average once every 100 sec , even if the previous one has not yet been sent (e.g., the stations can buffer outgoing frames). What is the maximum value of \( N \) ? Notes: Throughput Pure ALOHA is 0.184 and for slotted ALOHA 32\% 2. Give two reasons why networks might use an error-correcting code instead of error detection and retransmission. 3. Six stations, \( A \) through \( F \), communicate using the MACA protocol. Is it possible for two transmissions to take place simultaneously? Explain your answer. 4. Give two example computer applications for which connection-oriented service is appropriate. Now give two examples for which connectionless service is best. 5. If costs are recorded as 8-bit numbers in a 50-router network, and distance vectors are exchanged twice a second, how much bandwidth per (fullduplex) line is chewed up by the distributed routing algorithm? Assume that each router has three lines to other routers.

After a drunk driving accident, Adisa has been court ordered to see, Naseem, a therapist who specializes in alcohol-and-substance use disorders. Naseem practices from a harm reduction model and uses motivational interviewing as an primary therapeutic intervention. Although he meets criteria for moderate alcohol use disorder, when Adisa first comes in to see Naseem he denies having any problems with alcohol misuse and demonstrates no interest in changing his behavior with/relationship to alcohol. Through the therapeutic process, Adisa begins to see the negative impact his alcohol use has had on his life and starts to consider reducing alcohol consumption. However, Adisa really struggles with committing to reducing consumption or taking any steps in that direction. In a recent session he says to Naseem, "I don't want to end up with liver failure, like my dad, but I can't imagine giving up going out drinking with my friends--it's one of the few enjoyments I have in life." Based on the stages of change model, what stage was Adisa in when he first came into treatment and what stage does his statement to Naseem indicate he is in?
