## Homework Statement

Part c: A pendulum is attached to a 0.15m wooden bar sticked horizontally to a table by a string of 0.12m. If the system is revolved with a revolution speed of 1.5 rev per second, what is the angle θ the pendulum make with respect to the vertical axis?

## Homework Equations

Tsin θ =mrw^2

Tcos θ = mg

where r=0.15 +0.12 sin θ

## The Attempt at a Solution

To identify my mistake at how to solve this question as I can't get the answer provided which is 85.7 degree using my original equation. Instead, i get a value of 209 degree which sounded so impossible to occur.

Thanks for help.
