To determine the radius of gyration of given bar using bifilar suspensionmethod.
Uniform steel bar, cylindrical weights, stop watch.
Fig 1 shows the general arrangement for carrying out experiment. A
uniform rectangular section bar is suspended from support frame by twoparallel cords.

Two small chucks fitted in the frame and other endssecured in bifilar bar. Ends of these cords pass through a chuck so as tofacilitate for change in length of the cord it is possible to adjust length of chord by loosening the chuck.The suspension may also be used to determine radius of gyrationof any body,In this case the body under investigation is bolted to thecenter. Radius of gyration of combined bar and body is then determined.
1) Suspend the bar from chuck and adjust length of chord ' L' convenientlynote the suspension length of each cord must be same.2) Allow the bar to oscillate about the vertical axis passing through center of gravity and measure periodic time 'T' by knowing time for 20oscillations.3) Repeat the experiment by mounting the weights one equal distancefrom the center.
Consider bar AB whose moment of inertia is to be determine issuspended by two parallel strings as shown in figure 2.Let, L = length of each string.m = mass of bar.K = radius of gyration about the vertical axis through G.I = mass moment of inertia about the vertical axis through G.2r = distance between two stringsT = tension in each string
= angle of twist of bar.
= angle of twist of string
= angular accelaration of the bar.Initial position of bar is AGB. Now, if bar is set gently in vibration inhorizontal plane, it will start oscillating about vertical axis through its masscenter G. when bar is twisted about its C.G, through an angle
, bar is inposition A'GB' as shown. When bar is getting
as angular displacement,then string is getting
as angular displacement about vertical, distancemoved by point A is arc AA'
arc AA' = r

= r

It is to some extent but not completely. A poor man does not have much chances to earn a lot in order to come out of poverty. Consider yourself a man with an ordinary job with daily wadges. You also have a family to feed. You need to provide them shelter, food, education and health. You work 16 hours a day, 7 days a week but still not able to earn more than your expense.

Some time its your fate who does not allow you to grow and some time its your own fault.

Digital technology allows information to be copied and replicated precisely. It is due to digital technology that our society is now so defined by computers, smart phones, internet access, and cell phone communication.


  • By opening up so much knowledge to us - and presenting it at our fingertips - the Information Age allows evil to spawn and grow at an alarming rate. From the questionable to the perverted, from the dubious to the depraved, the same information can be presented to us instantly and transit the globe in moments, without allowing society time to sit back and consider the information or ideas that are offered to us.
  • A whole family can now live in a single house and yet live like single people, because this Revolution breaks down many relationships and our sense of community. While we can maintain friendships in distant states and countries, it breaks down all those friendships which are not actively fostered in the digital realm. When you get on a bus or train full of people on their smartphones, it reveals this sad truth: that everyone is connected, but only to those whom they chose to connect with.
  • Similarly, digital technology breaks apart our sense of political and regional community. This has been in decay for some time now, but the Information Age is tearing it apart faster than ever. The idea that we can choose our friends through social media, and stay connected with only those - without spending time with those who live and interact around us - tears down the idea that we live in a community, in a special place in the world. It tears down the idea that we need our neighbors on a political level, which prepares for the abuse of democracy.
  • Finally, the digital realm encourages passivism, rather than discernment. Having information presented on a screen (as it constantly is in the Information Age) welcomes viewers to sit back, accept the message that is presented, and move on without time for reflection. While movies and media all communicate messages, digital electronics have a strange way of obscuring that fact and encouraging passive consumerism. Television has been around for some time, but only multiply the problem.

There are several ways to solve this problem. I will present one of the ways. Let x be Jimmy's age - I always pick the lower age because most people find multiplication easier than division and fractions. Let 2x be his sister's age (twice as old as Jimmy) Let x + 5 be his big brother's age. Sum of the three ages is Jimmy's age + sister's age + big brother's age. (x) + (2x) + (x+5) - put them in brackets to show each person's age, but you don't need to. Finally, we get 4x+ 5 = 29. Subtract 5 from each side to isolate the 4x. 4x + 5 - 5 = 29 - 5 4x = 24 Divide both sides by 4 to get x by itself. 4x/4 = 24/4 x = 6. Now, I read the question over and see if I interpreted it correctly. Jimmy's sister is twice as old as he is. His big brother is 5years older than he is. The sum of their three ages is 29. How old is Jimmy's brother?
Jimmy is 6. His sister is 12. His big brother is 11. Adding them up I get 29. However, it asks for Jimmy's brother's age, not Jimmy's. Jimmy's brothers age is 11. Good luck, Paul
