223_45_1.JPGif the person donot bend, then there will be a nonzero torque due to centrifugal force(person as the non inertial frame). to avoid this, person bends. look at the next picture to understand this.

 

here u can see that the torque due to mg balances that due to centrifugal force.

hope, this makes things clear to u201_45_1.JPG

the 2nd diagram in the previous answer is wrong.

as the person bends right, here is the right figure.
