A uniform rod of length $200\text{cm}$ and mass $500\text{g}$ is balanced on a wedge placed at $40\text{cm}$ mark. A mass of $2\text{Kg}$ is suspended from the rod at $20\text{cm}$ and another unknown mass ${}^{\prime }{m}^{\prime }$ is suspended from the rod at $160\text{cm}$ mark as shown in the figure. Find the value of $m$ such that the rod is in equilibrium.

Q. A uniform rod of length $200\text{cm}$ and mass $500\text{g}$ is balanced on a wedge placed at $40\text{cm}$ mark. A mass of $2\text{kg}$ is suspended from the rod at $20\text{cm}$ and another unknown mass $m$ is suspended from the rod at $160\text{cm}$ mark as shown in the figure. Find the value of $m$ such that the rod is in equilibrium.

Q. A metal rod of length $50\text{cm}$ having mass $2\text{kg}$ is supported on two edges placed $10\text{cm}$ from each end. A $3\text{kg}$ load is suspended at $20\text{cm}$ from one end. Find the reactions at the edges (take $g=10{\text{m/s}}^2$)

Q. A metal rod of uniform thickness and of length $1m$ is suspended at its $25cm$ division with the help of a string. The rod remains horizontally straight when a block of mass $2kg$ is suspended to the rod at its $10cm$ division from same end. The mass of the rod is:

Q.

A rod of length 100 m is pivoted at a distance of 60 m from one end. A block of mass 10 kg is suspended at the other end of the rod. If the rod is in equilibrium, find the mass of the rod. Take acceleration due to gravity $g$ = $10m{s}^{-}2$

Q. A uniform rod of mass $2\text{kg}$ is hanging from a thread attached at the midpoint $\left(\text{O}\right)$ of the rod. A block of mass $m=6\text{kg}$ hangs at the left end of the rod and a block of mass $M$ hangs at the right end at a distance of $30\text{cm}$ from the mid point $\left(\text{O}\right)$. If the system is in equilibrium, calculate the mass $\left(M\right)$, given that overall length of the rod is $100\text{cm}$. Take $g=10{\text{m/s}}^2$.
