Engineering Mechanics - Equilibrium of a Particle - Discussion
Discussion Forum : Equilibrium of a Particle - General Questions (Q.No. 1)
1.
The joint O of a space frame is subjected to four forces. Strut OA lies in the x-y plane and strut OB lies in the y-z plane. Determine the force acting in each if the three struts required for equilibrium of the joint. Set 
= 45°.

Why to convert the unit from lb to newton (N) when the answer required is in lb ?
Simple question just based on laws of static equilibrium.
Ex=0
Ey=0
Ez=0

300=R*sin45
R=424
500=P*sin30
P=1000
And
F=P*cos30-R*cos45
F=1000*Sqrt3/2-424/sqrt2
F=566
R=424
500=P*sin30
P=1000
And
F=P*cos30-R*cos45
F=1000*Sqrt3/2-424/sqrt2
F=566

Sum of forces in a direction =0
taking
E Fx=0;
E Fy=0;
E Fz=0;
Solve it simple.
