Three masses are connected to a rotating shaft supported on bearings $A$ and $B$ as shown in the figure. The system is in a space where the gravitational effect is absent. Neglect the mass of shaft and rods connecting the masses. For $m_{1}= 10 kg, m_{2}=5 kg$ and ... $1000$ radian/s, the magnitude of the bearing reaction (in N) at location $B$ is ___________.

A manufacturer can produce $12000$ bearings per day. The manufacturer received an order of $8000$ bearings per day from a customer. The cost of holding a bearing in stock is $Rs$. $0.20$ per month. Setup cost per production run is $Rs$. $50 0$. Assuming $300$ working days in a year, the frequency of production run should be $4.5$ days $4.5$ months $6.8$ days $6.8$ months
