Default I need some help for a 6th grade project

I have made an arm that is suposed to move at an elbow joint and a grasp and oblect by pushing a button, but I have a problem with it. Everytime I will pull the string to move the elbow joint it breaks in half. When I pull the string to grasp an item it doesn't hold onto the object. I would really like the help!
