The simple 2-kg pendulum is released from rest in the horizontal position. as it reaches the bottom position, the cord wraps around the smooth fixed pin at b and continues in the smaller arc in the vertical plane. calculate the magnitude of the force r supported by the pin at b when the pendulum passes the position theta = 30o .
