The pipe is subjected to a force of 83 kN. Determine the moment of this force with respect to the z-axis.

The force of magnitude F=122 lb acts along the edge of the triangular plate. Determine the moment of F about point O. The moment is positive if counterclockwise, negative if clockwise. 10" B 25" F = 122 lb

Determine the sense of the moment at point O due to the application of the 50-N force. 50 N 100 mm 60 45 200 mm -100mm-

If F, = {110i - 120j + 95k} N and F2 = { -160i + 240j + 95k} N, determine the resultant moment produced by these forces about point O. Express the result as a Cartesian vector. 4 m F, 5 m. 3.5 m

The crank OA is shown. If OA = 57 mm, 0 = 60°, and 3= 65°, determine the moment of the force F of magnitude F= 29 N about point O. The moment is positive if counterclockwise, negative if clockwise. Answer: Mo- N-m

If F1=(140i+-150j+95k)kN, and F2=(-230i+280j+80k)kN, determine the resultant moment produced by these forces about point O. Express the result as a Cartesian Vector (Fill Mx, then My, then Mz). ( don't forget to put the sign for each component) My is 4m My is F2 Mz is 3m

Determine the moment of the force about point A as shown in the Figure below.
