). A 50 mm diameter cylinder is subjected to an axial compressive load of 80 kN. The cylinder is partially
enclosed by a well-fitted casing covering almost the whole length, which reduces the lateral expansion by half.
Determine the ratio between the axial strain when the casing is fitted and that when it is free to expand in diameter.
Take v = 0.3.

Apiping systems consists of 6 m of 6-std type k and 12 m of 4-std type k, both drawn copper tubing. the system conveys ethylene glycol at a rate of 0.013 m3/s. the pressure drop across the system is to be calculated. there are two 90° elbows in the 6-in pipe, a reduction from the 6-in pipe to the 4-in pipe and four 90° elbows in the 4-in pipe. all fittings are soldered (same as flanged) and regular. the inlet and outlet of the system are at the same height.
