Determine the moment about the origin O of the force F= 4i - 3j + 5k that acts at a point A . Assume that the position vector of A is (a) r = 2i + 3j - 4k, (b) r = 8i + 6j - 10k, (c) r = 8i - 6j + 5k.
Three concurrent forces P,Q and F have a resultant of 5 lb directed forward and up to the right at θx = 60⁰, θy = 60⁰, θz = 45⁰. P equals 20 lb and passes through the origin and the point (2,1,4). The value of Q is also 20 lb and passes through the point (5,2,3). Determine the magnitude of the third force F and the angles it makes with the reference axes.
I need to determine in vector notation the moment of the force about point O and point B
and also determine the magnitude of the 600N force about point O and point B
