Question 53: Laws of Motion

Question

A heavy iron bar, of weight $$W$$ is having its one end on the ground and the other on the shoulder of a person. The bar makes an angle $$	heta$$ with the horizontal. The weight experienced by the person is :

Accepted Answer

$$\begin{aligned}
& m g 	imes \frac{L}{2} \cos 	heta=N 	imes L \cos 	heta \
& \Rightarrow \quad N=\frac{m g}{2}=\frac{W}{2}
\end{aligned}$$

Answer

$$W \sin 	heta$$

Answer

$$W$$

Answer

$$\frac{W}{2}$$

Answer

$$W \cos 	heta$$
