The moment of force
Explanation:
Given:
A force of 100N,
angle of 60 degrees anticlockwise with the horizontal.
coordinates= (4,5).
moment of force :
F = 100( 1/2i^ + √3/2j^)
r = 4i + 5j
M = r x F
= 100 x (4i + 5j) x (1/2i + √3/2j)
= 100(2√3 R - 5/2R)
= 100(4√3 - 1/2)k
= 5.92 x 100/2
= 296N.m
hence, The moment of force is 296N.m
