We are given with the vectors
-F = 4i - 3j + 4k
and
F = -4i + 3j - 4k
To get the moment, we determine the cross product between the two vectors
-F x F = 0i + 0j + 0k
The magnitude is 0 but this is if the pivot is the origin. In the couple, the magnitude is 4.
Answer:
10580
Step-by-step explanation:
use partition to get 3x460 and 20x460
20x460=2x4600=9200
3x460=1380
9200+1380=10580
Answer:
L = 2W, and LW = 5000. Therefore 2W^2 = 5000, so W^2 = 2500. This means W=50 and L=100.
