Types of loading

In mechanical terminology, the term load indicates that external force/weight, either constant or variable, acts on a mechanical member/structure. The weight of an object of a specific material is also an external load, and the external force that works on a structure comes under the categories of loading. The external load generates its effects as stress and strain in the structure.

Question

Air contained in a variable-load
piston-cylinder is initially at 0.1 m3,
22°C, and 100 kPa. The cylinder is
then placed in a hot water bath at
100°C where the air begins absorbing
heat at a constant rate of 0.5 kW. After some time it is observed that the
temperature has remained relatively constant, however the volume has
doubled. Determine the amount of time (seconds) that has past.
Answer: At = 13.86 seconds
