Equilibrium of a Particle
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°.

F = 46.4 lb, R = 400 lb, P = 424 lb
F = 566 lb, R = 424 lb, P = 1000 lb
F = 11.3 lb, R = 424 lb, P = 577 lb
F = 1166 lb, R = 424 lb, P = 1000 lb

How did you come up with the value of p ?
Aditya said:   1 decade ago
Sum of force in z direction
-500 + p sin30 = 0
p=1000
sum of force in x direction
300 - r sin45 =0
r = 424.26
sum of force in y direction
p cos30 - r cos45 = f
f = 566.025
