Homework Statement
There is a uniform slender bar which is suspended by two light inextensible strings and hangs in equilibrium. (if the mass and length of the bar are m and 2b )
Now, someone slightly knocks one end to make the bar rotate around the vertical axis with initial angular velocity ω0.
I want to know two things
(1) what is the tension in the strings when the slender bar begins to rotate?
(2) What is the rotation angle of the bar when the center of mass reaches its highest position?
Homework Equations
[/B]
ΣF=0,ΣMG=0 equilibrium equations
ΔT=−ΔV Low of conservation of mechanical energy
The Attempt at a Solution
Can I use the equilibrium equations and conservation of mechanical energy for these problems?
