4. Mr. Doofus McFly decides he is going to put a square peg in a round hole, both initially at 83.00°F. The square peg is made of lead and is 3.500cm on a side and the circular hole is 4.925cm in diameter. With the temperature of the piece with the round hole held constant, the temperature of the square peg is changed until it just barely fits inside the round hole. Calculate the temperature at which that occurs in degrees Celsius. The coefficient of linear expansion for lead is 29.00 x 106°C-!.
