A body of weight W N rest on a smooth plane inclined at an angle(theta)o to the horizontal. What is the resolved part of the weight in Newtons along the plane?
-
A.
W sin(theta) -
B.
W cos(theta) -
C.
W sec(theta) -
D.
W tan(theta)
Correct Answer: Option A
Explanation
horizontal component = W cos(90o – (theta))
= W sin
