Replace the force system acting on the frame by an equivalent resultant force, and specify where the resultant's line of action intersects member AB, measured from point A. 40 lb B 2 ft 20 lb 5 ft y A 5 ft X 50 lb 5 4 3 -2 ft

Replace the three forces shown by an equivalent force-couple system at point A. If the forces are replaced by a single resultant force, determine the distance d below point A to its line of action. Answers: R= i M= i 160 N 290 N d = Single resultant force. i www Force-couple system at A. The force is positive if to the right, and the couple is positive if counterclockwise. 300 N 650 mm 650 mm 650 mm N N.m mm

C2X8 X Given the 50 lb. force at point A, replace it by a force acting at B. 6" A

Part II: Determine the magnitude of force F3 if the resultant of all three forces is directly above the support at B. F=100 lb. 4' 6' F₂=200 lb. 6' 6' C

Q.5) Three forces are applied to bracket as shown in figure below. Replace the given force system by a resultant force system acting at point O. Then replace the resultant force system by the simplest resultant and locate its line of action as it passes through the y-z plane. y 800 N -ve z 70 mm 40 mm C 40 mm 120 mm Z 245° - X 1000 N 600N 60° D E(150 mm, -50 mm, 100 mm) 110 mm B/ y 1 45° 30° X

Solve it within 20minutes , Include FBD.

Replace the three forces shown by an equivalent force-couple system at point A. If the forces are replaced by a single resultant force, determine the distance d below point A to its line of action. 110 N 710 mm 710 mm 710 mm 185 N Answers: Force-couple system at A. The force is positive if to the right, and the couple is positive if counterclockwise. R= i N M= i Single resultant force. d= 100 N N-m mm

Three forces act at point O. If it is known that the y-component of the resultant R is -3.9 kN and that the z-component is 3.0 kN, determine F3, 0, and R. Answers: F2 = 5.0 kN F₁ = 4.3 KN F3= KN 0 = R = KN

Replace the force system acting on a plate by a single force and determine where the line of action of this force intersects the x-axis and the y-axis. y 180 N 240 mm- 300 N 70° 15° 63 N.m 120 N 500 mm 60 N.m 180 mm 150 mm -300 mm- X -600 mm-
