Question 2 1. Using scalar notation, determine the magnitude of the resultant moment at point A if F= 7 kN. 2. Determine the required magnitude of the force F, if the resultant moment on the beam is to be zero. A 3 m 4 KN 4 30° -F 3 5 B 3 m 0.5 m 0.5 m TOW 3 F 30° 5 3 kN

As shown in the image below, the rigid member ABC is subjected to three forces. The forces are F1=3.3kN, F2=3.9kN, and F3=2.0kN, and the angles are alpha=47 degrees and beta=29 degrees. Determine the total moment (in kN*m) caused by three forces about point A. Negative sign must be included in the moment is clockwise.

Determine the moment about point B of each of the three forces acting on the beam using the Scalar Approach / Notation. F₁ = 375 lb 8 ft 6 ft 3 4 F₂ = 500 lb 5 ft- B 0.5 ft 30° F3 = 160 lb

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
