A cylindrical rod 120mm long and having a diameter of 15mm is to be elastically deformed using a tensile load of 35000N. Calculate its elongation.

Apiston-cylinder with a volume of 0.25 m3 holds 1 kg of air (r 0.287 k/kgk) at a temperature of 100 c. heat transfer to the cylinder causes an isothermal expansion of the piston until the volume triples. how much heat is added to the piston-cylinder?

What precautions should you take to prevent injuries when dealing with heavy loads?
