Torsion

In mechanical engineering, torque, torsion, and twisting moment are three of the most important concepts which have different meanings. Torque is the consequence of a moment of a force that produces an angular acceleration in a body or induces rotational kinetic energy in a body. For instance, in an automobile, the power transmission shaft is a body that is always under rotation due to the external torque acting on it, this torque is created by the engine.

|Read the problem statement and the solution provided. There may or may not be one or more mistakes in the solution. Go through the solution carefully and then do the following. 1. State if the solution is correct or incorrect 2. If the solution is incorrect, identify what is the mistake in the solution. Be specific and succinct. 3. If the solution is incorrect, provide the final solution with appropriate steps. You can make the corrections directly on a copy of this provided solution, but make sure you clearly explain the corrections. Problem: Consider fully-developed flow of water through a 24-cm diameter tube. The water comes in at 20°C and exits at 40°C. The surface temperature of the tube is uniform at 60°C. The water flow has a mass flow rate of 0.24 kg/s. What is the average convection coefficient of the water flow? Solution: We have T, = 60°C, Tmi = 20°C, Tmo = 40°C, So, the bulk-mean temperature is Tm = 30°C. The appropriate properties are: u = 7.98 × 10-4 kg/ms; k = 0.615…
