Apolymeric cylinder initially exerts a stress with a magnitude (absolute value) of 1.546 mpa when compressed.
if the tensile modulus and viscosity of this polymer are 14.7 mpa and 2 ×1012 pa-s, respectively, what will be the approximate magnitude of the stress, in mpa, exerted by the spring after 1.5 day(s)?

The force on a cutting tool are 2600n vertically downward and 2100 horizontal. determine the resultant force acting on the tool and the angle at which it acts.

Apipe with an outside diameter of 15 cm is exposed to an ambient air and surrounding temperature of -20°c. the pipe has an outer surface temperature of 65°c and an emissivity of 0.85. if the rate of heat loss from the pipe surface is 0.95 kw per meter of length, the external convective heat transfer coefficient (h) is: (a) 12.5 w/m"k (b) 18.6 w/mk (c) 23.7 w/mk (d) 27.9 w/mk (e) 33.5 w/mk
