Question

Forces P and F acting along the bar shown in the figure, to maintain equilibrium of pin A. determine the value of P and F. ​

Answer 1

Answer:

ΣFH=0  

F(35)=P(15√)+30

F=5√3P+50       →   Equation (1)

 

ΣFV=0

P(25√)+F(45)=18

5√2P+F=22.5

 

Substitute F of Equation (1)

5√2P+(5√3P+50)=22.5

55√6P=−27.5

P=−14.76 kN           answer

 

From Equation (1)

F=5√3(−14.76)+50

F=39 kN           answer
