공학도를 위한 정역학 솔루션 2장~10장

PROBLEM 2.1
Two forces are applied to an eye bolt fastened to a beam. Determine
graphically the magnitude and direction of their resultant using (a) the
parallelogram law, (b) the triangle rule.
SOLUTION
PROBLEM 2.2
The cable stays AB and AD help support pole AC. Knowing that the
tension is 500 N in AB and 160 N in AD, determine graphically the
magnitude and direction of the resultant of the forces exerted by the stays
at A using (a) the parallelogram law, (b) the triangle rule.
SOLUTION
PROBLEM 2.3
Two forces P and Q are applied as shown at point A of a hook support.
Knowing that P 15 lb and Q 25 lb, determine graphically the
magnitude and direction of their resultant using (a) the parallelogram law,
(b) the triangle rule.
