resultant of parallel forces

Problem 243
The resultant of three parallel loads (one is missing in Fig. P-243) is 13.6 kg acting up at 3 m to the right of A. Compute the magnitude and position of the missing load.
 

Problem 242
Find the value of P and F so that the four forces shown in Fig. P-242 produce an upward resultant of 300 lb acting at 4 ft from the left end of the bar.
 

Problem 241
Locate the amount and position of the resultant of the loads acting on the Fink truss in Fig. P-241.
 

Problem 237
Determine the resultant of the four parallel forces acting on the rocker arm of Fig. P-237.
 

Problem 236
A parallel force system acts on the lever shown in Fig. P-236. Determine the magnitude and position of the resultant.
