4 questions for engineering physics class. work can be included if needed but is not required.

1. The horizontal distance from point o to the line of action of the resultant of the given forces is 15.5ft.
Resultant F = 4000+3500-4500+3000 = 6000lb (considering downward force as positive)
horizontal distance from point o to the line of action of the resultant
(4000*20) + (3500*14) –...
