Calculate the increase in tension in the string holding up the bob in the rotating chair. Calculate the tension when the bob is hanging vertically and the tension when the chair is rotating. H=65.3cm Ro=32cm The bob is 20.0g
I found that the Tension in the string when the bob is hanging vertically to be
T1=Fg=196N
I drew a free body diagram and my equations are Tcos(theta)=mg and Tsin(theta)=m(v^2/r)
So I would find the Tension in the string when the chair is rotation by using the equations
T=mg/cos(theta)
I am not sure how to find theta. I know the adj side is equal to the height 65.3, but how do I find the radius?
