Answer:
x = 1.018 m
Explanation:
given,
height of man = 190 cm
= 1.9 m
scale reading on left = 450 N
scale reading on the right = 390 N
Let center of gravity of man be x distance from feet, feet is on right side.
For system to be in equilibrium moment about center should be equal to zero.
∑M = 0
now,
450(1.9 - x ) - 390 × x = 0
450(1.9 - x ) = 390 × x
855 - 450 x = 390 x
840 x = 855
x = 1.018 m
hence, point of center of gravity from feet is equal to x = 1.018 m
Answer:
| w | = w√ ( sin^2 ∝ + cos^2∝ ) shows that w is independent of time hence it is constant
Explanation:
prove that the magnitude of <em>w</em> is constant
