Acylindrical specimen of some alloy 8 mm (0.31 in.) in diameter is stressed elastically in tension. a force of 15,700 n (3530 lbf) produces a reduction in specimen diameter of 5 * 10^-3 mm (2 * 10^-4 compute poisson's ratio for this material if its modulus of elasticity is 140 gpa (20.3 * 10^6 psi).

When at a point two solid phase changes to one solid phase on cooling then it is known as a) eutectoid point b) eutectic point c) peritectic point d) peritectoid point

The higher the astm grain-size number, the coarser the grain is. a)-true b)-false

For each of the following process: a) sketch the p-v diagram, b)sketch t-s diagram, c) sketch t-v diagram, d) sketch the boundary work on one of the diagrams (a, b or c) and e) sketch the reversible heat transfer on one of the diagrams (a, b or c): 1- isobaric process from compressed liquid to superheated vapor 2- isothermal process from compressed liquid to superheated vapor 3- isentropic process from compressed liquid to superheated vapor
