Q1/ It is required that the resultant force acting on the eyebolt in Fig. below be directed along the positive x axis and that F2 have a minimum magnitude. Determine this magnitude, the angle e and the corresponding resultant force * F:=700 N 60 F2 O e=30, FR=400 N, F2=D450 N O e=45, FR=300N, F2=20ON O e=60, FR=600N,F2=250 N O e=90,FR=350N, F2=606 N O Other:

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.

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
