• Heat and Temperature: Thermal expansion

  79329 Heat and Temperature: Thermal Expansion A brass ring of diameter 10.00 cm at 20.0 degrees C is heated and slipped over an aluminum rod of diameter 10.01 cm at 20 degrees C.

• Example for laws of thermodynamics

  Use your knowledge of thermodynamics to explain why nobody ever won the reward. Be specific. The laws of TD state that heat would flow from a hotter rod to a cooler one.

• Thermodynamics & Newton's law of cooling

  A long cylinderical rod of radius R is attached to a source of heat at one end and its surroundings are at temperature Ro. Show that at time t, temperature of the rod T(x,t) obeys the given equation (see attachment).

• Thermal Expansion

  To what temperature would a constrained rod of aluminum with a diameter of 50 mm need to be heated, if it is expected to exert a force of 200 KN?

• Temperatures of two similar metal spheres differently fixes in the space. Why is that?

  The first is pended on the end of a rod and the second is propped up (supported) by the similar rod. Both are heated with the same quantity of heat Q. Will the temperatures of these two spheres be equal?

• Temperatures of two metal spheres fixed in space: Explain applied energy distribution

  The first is pended on the end of a rod and the second is propped up (supported) by the similar rod. Both are heated with the same quantity of heat Q. Will the temperatures of these two spheres be equal?

• Partial Differential Equations (Dirichlet Boundary Condition; Separation of Variables)

  Suppose that the rod is initially heated to a temperature of T uniformly throughout the tod, and is dropped into a bucket of ice water at t = 0.

• Temperatures for a Ring to Slip Over a Rod

  If both are heated together, what temperature must both reach so that the ring just slips over the rod? Would this process work? Please see the attached file.

• Metal linear expansion problems

  Because the ball initially just fit the ring, when heated its volume will increase, so it will NOT fit the ring anymore. If you heat the ring only: This is better understood by realizing that the ring in reality is a rod bent into a circle.
