Hi,
I am interested in calculating the force required to keep a pendulum in motion. I believe This force will be same as the frictional loss + other dampening loss happening in the oscillations.
now,
I know the initial push or force that i am giving to the pendulum. let initial force given to pendulum be 3.5 Kg force-cm.
I also know the displacement angle of pendulum. The displacement angle A= 20 Degrees.
The length of the pendulum is L=30 cm. and the weight of the pendulum is W=10 Kg.
The pendulum oscillations dies out after say 40 cycles.
Can i calculate how much energy is lost in the pedulum during this 40 cycles?
How can i calculate the energy loss per cycle from this?
My ultimate aim is to calculate the force required to be given to the pendulum to keep it moving.
Can some one please help?
Thanks
