Thanks. This link worked and I got the figure. I will try to upload the answer today itself.
Expert:  akch2002 replied 1 year ago.
Reactions, bending moment and shear force have been calculated. For calculating deflection, moment of inertia(I) is required. For this, beam cross section is required.
Something about beam is given in top most right corner. I just want to confirm it.
Expert:  akch2002 replied 1 year ago.
Here are answers. Kindly forward moment of inertia value so that deflection can also be calculated.

Inertia=103 in4

Customer: replied 1 year ago.


inertia=103

Customer: replied 1 year ago.


inertia=103.... Remember you are calcuating deflection for L/2 and Deflection Max at the bottom..

Expert:  akch2002 replied 1 year ago.
Thanks. I will calculate it shortly.
Customer: replied 1 year ago.


The answer I have is .34 In


 


1st one is =.28


and the 2nd on is=.06 in


 


Which gives me total of .34 in..I get the answer my problem is doing diagram..I dont understand..can you check to see if I have the righ answer or not?

Expert:  akch2002 replied 1 year ago.
Thanks for rating answer as excellent.
What formulas are given for calculating deflection in answers are for deflection at L/2. We have to put the numerical values and calculate deflection.
I want some clarification regarding units.
Distributed load = 1 kips, what is this kips; kindly describe it.
Moment of inertia = 103in^4; is it correct as unit of moment of inertia is in mass-distance^2. Kindly check it.
Customer: replied 1 year ago.


1 kips=1000 poung


Inertia was given in the book for the steel w12 x16


 

Customer: replied 1 year ago.


1000 pound


 

Expert:  akch2002 replied 1 year ago.
OK. I will calculate now.

It was given in the book...so use the I I provided to you..N pass me the answer with less then one hour..because I will have to hand it with in an hour. I=103 E=30x10^3

Expert:  akch2002 replied 1 year ago.
d = [2000*(14*12)^3/(48*30000*10^3*1000)]+[ 5*(1000/12)*(14*12)^4/384*30000*10^3*41000]=0.035in
