एक 50 N का बल क्षैतिज से 60° का कोण बनाता है। इसका ऊर्ध्वाधर घटक (vertical component) क्या है?

According to the perpendicular axis theorem, the moment of inertia of a plane area about an axis normal to the x-y plane passing through the origin is given by:

The expression for the moment of inertia of a rectangular section of width 'b' and depth 'd' about an axis passing through its base is:
