Acylindrical bar of metal having a diameter of 18.7 mm and a length of 200 mm is deformed elastically in tension with a force of 53200 n. given that the elastic modulus and poisson's ratio of the metal are 66.3 gpa and 0.32, 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.

If forces acting on an object are unbalanced, which factors may result fron an unbalanced force? check all that apply

Animals respond in various ways to stimuli detected through their senses. some of these responses are stimulated by the presence of danger. which of these animal responses is the best example of a response to an immediate threat? a) a rooster crows every morning at the first sign of light. b) as something approaches an octopus, it shoots a cloud of ink. c) from late fall until spring, bears hibernate to preserve energy. reactivate d) a dog is getting hot in the sunlight, so he moves to a shaded area.

The system is released from rest with the cable taut, and the homogeneous cylinder does not slip on the rough incline. determine the angular acceleration of the cylinder and the minimum coeffi cient s of friction for which the cylinder will not slip.
