You are holding a bulletin board weighing 5.85 N in place against a wall while your friend secures it to the wall. To keep it from slipping, you apply a force perpendicular to the bulletin board, pressing it directly into the wall. How large must this force be if the coefficient of static friction with the wall is 0.39?
Can someone help me with this friction problem? Thank you so much!

I hope he hits the right nail! (lol)

You are holding a bulletin board weighing 6.82 N in place against a wall while your friend secures it to the wall.

You are holding a bulletin board weighing 6N in place against a wall.?

For the board to not slip, the net force f = ma = W - F = 0 That is the friction force F exactly offsets the weight W of the board.

W = 6 Newtons; so F = W = 6 Newton = kN and N = F/k = 6/.4 = 15 Newton. ANS.

When I was a cop, which mostly pre-dated the computer technology we take for granted today, a major investigation might include the creation of a link chart on a bulletin board, showing people, locations, cars, etc., some connected by lengths of string or yarn. Really creative people would use different colors of yarn to show different types of links. I saw announcements from organizations that taught week-long workshops in the creation and maintenance of these charts. One of the problems in creating one of these charts was that they took up a lot of room. Our detective bureau of maybe 25 officers had a single large bulletin board where such a chart could be posted, and there were often several major cases (plus numerous minor or routine cases) working at one time. The chart had to be covered most of the time, as a suspect or a friend of a suspect might see it and get a leg up on the investigation. All told, they weren't very practical. The big displays you see on TV programs like Law and Order: SVU reinforce the myth that detectives work on a single case at a time. In shows like these, usually the entire squad is devoted to investigating a single incident or group of incidents. The wall display is a device to move the story along and reinforce the relationship of the players. You're reminded of who the suspects and victims are, what sort of things they did, etc. I quietly marvel at how the detectives have managed to obtain great, well-exposed, high-resolution photos of all the players. Photos like that might be possible to obtain, given enough time and effort, but many of them would be from driver's license files and photocopies of old mug shots, and would vary a lot in quality. Cops do still use link charts, but they're more helpful in complex, longitudinal investigations where there might be hundreds of people, places, phone numbers, IP addresses, etc. involved. The most popular software for managing this kind of information is called i2 Intelligence Analysis Platform. The product was purchased by IBM several years ago. i2 produces charts for display on a computer screen, and are zoom-able, so the user can reveal greater detail. While you might find one of the simpler board displays in a detective office, it's far more likely this sort of thing will be kept on a computer.

Really dangerous setup there. A cat might jump from table to rail with every reasonable expectation of landing on it for a leisurely walk…only it’s round, and it’s metal, so one bit of thrust too much and it will go over the other side, with nothing to grab onto. No matter how good its instincts about not jumping off the balcony (questionable anyway) this is a tragedy waiting to happen.You can get a cat enclosure or….put up netting. There are companies that make cat netting systems, but with a small enclosed balcony you don’t need that. Whip up a wooden frame the size of the opening, staple deer netting over it, and just secure it upright however that works best. The cat *will* try to climb it, so make sure it’s in place solidly enough to stand up to that. Or you could put up a few vertical supports and tie them to the top and bottom of the glass supports…whatever will give you something to staple net to.Deer netting is what cat fencing companies use, and you can get it cheaply on amazon in big enough pieces to cut this in one panel. It is hair thin and almost invisible, so it won’t impact your enjoyment of the patio. Don’t worry about pulling it taut; cats hate climbing loose fabric, so a little slack discourages them from trying. Cover the entire opening so you never have to worry about your cat being out there.(You could just staple the netting to any wood on the patio, but if you are renting you may not want to do that.)BTW, it looks like there is a cat sized space leading to the neighbor’s balcony. Don’t forget to close that off.

I started selling online when eBay just got started. I used PayPal to secure payment. The very first thing I sold was items that would fall off creatures in a game called Everquest. Later they were deemed intellectual property and individuals were not allowed to sell similar items legally any longer.The wife would play the game while at home raising our kids and when I got home I would list the items and handle the transfers using another account. We had a solid 17 month run averaging $4800 per month the highest month making $7800.Interestingly there were two markets. One market was what people would pay in cash on eBay for items and the other market was the in game market where people would use platinum pieces to buy items. There was a time when you could buy 500,000 platinum pieces ( PP) on eBay for $500. You could then break that up and sell in lots of 1000 PP for $9.99 and 2500 PP for $19.99. Big players did not want the hassle of selling such small lots and until others caught onto what I was doing it was quite lucrative. There were lots of people who would buy the smaller lots of PP.I also remember a an item called the FUNGI TUNIC that could be bought in game for 34,000 PP, but would sell on eBay for $500 -$700 cash. There were many items you could play the two markets against each other and profit. It took a lot of understanding of the game and having the ability to get good items. The best route was buying the large amounts of PP on eBay using that to buy in game items to then bring back to eBay and sell.Like I said it was good for some 17 months and quite the income while it lasted.
