Auniform bar has two small balls glued to its ends. the bar is 3.00 m long and with mass 2.40 kg , while the balls each have mass 0.700 kg and can be treated as point masses. you may want to review (page) . for related problem-solving tips and strategies, you may want to view a video tutor solution of an abstract sculpture. part a find the moment of inertia of this combination about an axis perpendicular to the bar through its center. express your answer in kilogram-meters squared.

Ok i am attempting to my niece attach a galvanized wire (like a tether for a dog) at the corner of two fences, making a tightwire if you will and we drilled a hole in a softball and she hits it. the ? and problem is that we can not get the wire taunt enough where it doesnt sag after hitting the ball once, and the wire sags and wobbbles. its a 15 ft rubber covered galvanized wire and one can adjust the length of the placing of the wire by having it make the corner of 2 fences become a it can be adjusted, however, with all our human strength and pliers we could not make it taunt as possible. is there anything other that attaching it to a car to do this. sorry abt the length but it would mean the world to my niece if i could solve this came up with the entire idea herself, and she is 14 and paid for the wire and did as much work as i did drilling a hole through a softball wide enough for attaching piece at each end of the wire that clips on to the fence. . any ideas welcome if serious. but awesome if it is a fact. much obliged. bucky bukowski buckman
