1. A circular disc mounted on a shaft carries three attachedmass of $4\mathrm{kg},3\mathrm{kg}$ and $2.5\mathrm{kg}$ at radial distances of $75\mathrm{mm},85\mathrm{mm}$, and $50\mathrm{mmat}$ relative angular position of $45^{?},135^{?}$, and $250^{?}$ with respect to the $\mathrm{x}$-axis respectively. Determine the amount of balancing weight and itsangular position to statically balance the system if the balance mass is to be located at a radial distance of $75\mathrm{mm}$.
