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...
