3. An electrical conduit is held in place by brackets A, D and E. The effect of the bracket at A on the conduit can be represented by the force F as shown. Determine the resulting moment that F produces that tends to twist the portion CG of the conduit about its axis. F = {-20i + 12j + 16k} N

Step 1
First, we need to find the distance between the point of application of the force F and the axis of rotation of the conduit. This distance is the perpendicular distance from point G to the line of action of the force F. We can use the formula for the distance Show more…

Determine the moment of the force at A about point P. Use a vector analysis and express the result in Cartesian vector form. A. Mp = (160i+240j+40k) N-m B. Mp = (280i+200j+400k) N-m C. Mp = (40i+80k) N-m D. Mp = (380i+160j+400k) N-m F = (40i+60j-20k) N

Determine the moment of the force F about an axis extending between O and A. Express the result as a Cartesian vector (i, j, k components). Hint: First determine unit vector OA. Next, set up your moment equation r x F. Lastly, the Cartesian form is the moment multiplied by the unit vector. F = {-40i - 120j + 80k} N 0.3 m 0.8 m 0.6 m
