Homework Statement Determine the magnitude of the moment of the force F about the axis CA of the tripod ABCD, if F = {40i -30j -100k}N. Image attached. 2. The attempt at a solution Based on a similar question I found in the textbook my method to solve this question: Find UCA =...

How did you calculate this? I have used u = F(Coord)/F(magnitude) = (Fx/F)i + (Fy/F)j + (Fz/F)k F (aka RDA) = (XA-XD)+(YA-YD)+(ZA-ZD) = (0-0.2)+(0-0.1)+(0-(-0.1)) = -0.2i - 0.1j + 0.1k magnitude = √0.06 Which is how I have got: UDA =...

Homework Statement (i) Find the resultant force acting at point D and write it in Cartesian form. (Note that CD is parallel to the y-axis, the 40N force acts parallel to the z-axis and the 30N force is parallel to the x-axis.) (ii) Find the magnitude of the projected component of the...
