Problem 26

An 85.0-N backpack is hung from the middle of an aluminum wire, as the drawing shows. The temperature of the wire then drops by 20.0 C8. Find the tension in the wire at the lower temperature. Assume that the distance between the supports does not change, and ignore any thermal stress

Physics 211, Week 4 Notes PSU: Fall term Physics is a study of what can cause an object to accelerate. That cause is a Force.  Force: a push or pull on an object Newtonian Mechanics: relation between a force and the acceleration it causes 1. Newton’s first law: If no force acts on a body, the body’s velocity cannot change; that is, the body cannot accelerate (object at rest, with no additional force, stays at rest). If no net force acts on a body (Fnet=0) the body’s velocity cannot change 2. The net force on a body is equal to the product of the body’s mass and it’s accelerating I. Force = Mass * Acceleration (F=m*a) II. Force ne
