Homework Statement
A tank 1.5m high stands on a trolley and is full of water .it has an orifice of diameter 0.1m at 0.3m from the bottom of the tank.if the orifice is suddenly opened coefficient of discharge of the orifice is 0.60, then find propelling force on the trolley.
Ans: 67.39N
Homework...
I was able to get the answer, however, I am not totally convinced. It's like:
We know tensile stress would be σ= 32 M / Πd^3
Now bending moment M will be due to the eccentric loading as well as due to the centrifugal force acting on the rod as a result of rotor's CG rotation.
So, M= m.g.e...
