block mass = 200 kg is sitting on a smooth surface
F1= 500 N
F2 = 650 N
F3 = 900 N
FP = concurrent at the center of the block
unit vectors are:
e1 = 2/3(((rad(3)/2)i) + (rad(3)/2)j + rad(3)/2k
e2 = rad(6)/3(rad(2)/2i - rad(2)/2j - rad(2)/2k
e3 = 2/3(1/2i + j + k)
What is the resultant R of the 3 external forces f1, F2, and F3,
What is the normal force N for any angle between 0 and 90
What is the force P to keep the system in equilibrium for the angles specified?
