Balsta reakciju aprēķināšana:
∑MA= ( Pq*5)+(Pq*10)+ (P1*10)+(0,5Pq*15)+(P2*20)-VB*30=0
VB = (200+400+600+300+400)/30 = 63,33 kN
∑MB = - (P2*10 )- (0,5Pq*15)- (Pq*20)- (P1*20 )- (Pq*25)-(0,5 Pq *30)+ VA*30=0
VA = (200+300+800+1200+1000+600)/30 = 136,67 kN
Pārbaude:
∑X = HA = 0
∑Y = VA+ VB - P1 - Pq – Pq - 0,5Pq - 0,5Pq -P = 0
(63,33+136,67)-(60+40+40+20+20+20) = 0
200-200=0
0=0…
