Need some assistance with this.
l = 1.95 mm. w= 1.89 mm. h= 5.82 m.
Coordinates for Point A is A(2,2,2)m
Coordinates for Point D is D(2.25,2.5,0)m
Force F acts along EA, (Magnitude is 55N)
Force P acTS along AD
1. What is force F in Cartesian Vector form. (Fx, Fy, Fz)
2. If we are calculating the moment that Force F creates about point B, WHAT
3. If we are calculating the moment that Force P creates about point B , WHAT vectors will be used ?
4. What is BC as position vector rBC. ( rBCx, rBCy, rBCz )
5. What is BC as unit vector uBC. (uBCx, uBCy, uBCz )
6. What is the moment that F creates around B ? (MB)
7. What is the magnitude of the moment that F creates around axis BC. ( |MBC| )
As per the guidelines, I can solve only first three subparts. For rest parts, repost in a separate post.
Given data,
Coordinates of A = (2, 2, 2) m
Coordinates of D = (2.25, 2.5, 0) m
From the diagram
Coordinates of E = (0, 0, h) = (0, 0, 5.82) m
Coordinates of B = (l, 0, 0) = (0.00195, 0, 0) m
Coordinates of C = (0, w, 0) = (0, 0.00189, 0) m
Force F = 55 N
