00:01 Later reaction at point a is ra and at b is rb taking moment about point a taking moment about point a so you can write the expression as 4 minus 8 multiplication 4 by 2 minus 20 multiplication 4 plus r b multiplication 8 is equal to 0 so you will get the value of r b as 18 kilo newton this is the value now going forward and solving the problem further similarly i can write summation of f is equal to zero or r a minus eight multiplication for minus 20 plus r b is equal to 0 or r a will be equal to 32 plus 20 minus 18 that is equal to 34 kilo newton as the value of r a so this is the value of r a 34 kilo newton and r b is 18 kilo newton now take section ac so at section ac consider left portion consider x from a so first let us draw the diagram here just look at it carefully this is point a and here you can write the different value as a follow just look at it carefully here the this value is 8 kilo newton per meter 8 kilo per meter and this distance is x this distance is x here you can write the value as mx here 34 kilo now you can write a expression as mx plus 8 x multiplication x by 2 minus 34 x is equal to 0 so the value of mx will be equal to 34 x minus 4 x square now taking at section cb at section cb you can write the diagram like this just look at it carefully this is point b and here you can write this distance as x here the value is 18 kilo newton or minus mx plus 18 x is equal to 0 so mx will be equal to 18 x now finally you can draw the diagram like this note that vertical displacement of point c of the beam we need to find so beauty vertical structure by putting on unit load at c then go for section moment in virtual structure so let us see the diagram first so this is the rough diagram which i am drawing here here this point is point a this point b here you can write the value as r a here it is r b this is point c here the value is 1 kilo newton here the value is 4 meter this distance is also 4…
