A cylindrical bar of metal having a diameter of 20.1 mm and a length of 204 mm is deformed elastically in tension with a force of 47500 N. Given that the elastic modulus and Poisson's ratio of the metal are 67.0 GPa and 0.33, respectively, determine the following: (a) The amount by which this specimen will elongate in the direction of the applied stress.
(b) The change in diameter of the specimen. Indicate an increase in diameter with a positive number and a decrease with a negative number.

According to newton's second law, when the same force is applied to two objects of different masses, a the object with greater mass will experience a great acceleration, and the object with less mass will experience an even greater acceleration, b. the object with greater mass will experience a smaller acceleration, and the object with less mass will experience a greater acceleration, c. the object with greater mass will experience a greater acceleration, and the object with less mass will experience a smaller acceleration, d. the object with greater mass will experience a small acceleration, and the object with less mass will experience an even smaller acceleration.
