Prob.4-15

David · Accepted Answer

Prob 4-1 
              RA+RB= 6kN 
Taking moment about B 
RA*6 + 20 =6*4 
RA= 2/3kN 
RB=16/3kN
At C 
Vc=2/3kN 
Mc=2/3*1=2/3 kNm 
Nc=0kN as there is no horizontal force
At D 
Vd =2/3 – 6 = -16/3kN 
Md=-28/3kNm 
Nc=0kN as there is no horizontal force
Prob 4-2
Internal normal force = 0 as there is no axial force or external force component parallel to x axis. 
Take moment about A; 
10*20 + 25 = R2*30 + 25 
 R2 = 20/3k 
So, R1 + R2 = 10 
 R1 = 10 – 20/3 = 10/3k 
Consider the following sections,
Mc = 25 + 10/3*10 = 175/3 k.ft 
Vc = 10/3 k
MD = 25 + 10/3*20 = 275/3k.
