Determine displacement (in) of a 1.28 in diameter steel bar, which is 50 ft long under a force of 21,672 lb if elasticity modulus is 30 x 10^6 psi. make sure you do not round up your answer to less than 4 significant (non-zero) figures.

Acompressor receives the shaft work to decrease the pressure of the fluid. a)- true b)- false

Aturning operation is performed with following conditions: rake angle of 12°, a feed of 0.35 mm/rev, and a depth of cut of 1.1 mm. the work piece is aluminum alloy 6061 with t6 heat treatment (a16061-t6). the resultant chip thickness was measured to be 1.0 mm. estimate the cutting force, fc. use shear stress of 207 mpa and coefficient of friction on the tool face of 0.6.

Select any two (2) areas of applications of chain-drive. (clo4) a)-permanent lubrication necessary b)-hydraulic forklift truck operation c)-rigging and heavy moving materials d)-relatively high maintenance costs e)-costlier than belt drives
