A simple pendulum consisting of a mass M attached to a string of length L is released from rest at an angle α. A pin is located at a distance l below the pivot point. When the pendulum swings down ,
the string hits the pin as shown in figure. The maximum angle θ which the string makes with the vertical after hitting the pin is: ,
