Sum the vertical forces:
C+W-69*9.8-203=0
C+W= ? you do it.
Then sum moments about either end. I will Sum moments about Will.
1*69*9.8+2*203-C(1.4)=0
solve for Cliff here, then put it in the first equation, solve for Will
Cliff and Will are carrying a uniform 2.0m board of mass 69kg. Will is supporting the board at the end while cliff is 0.6m from the other end as shown in the following figure. Cliff has attached his lunch to his end of the board, and the tension in the string supporting the lunch is 203N. Find the normal forces exerted by Cliff and Will.
