Find the temperature rise for the following parameters during compression of ti-6al-4v. average stress=1gpa, total strain=100%, density = 4500kg/m3, cp =540 j/kg. k. assume that 90% of the work done during compression goes into heating up the material.

An electrical motor raises a 50kg load at a construct velencity .calculate the power of the motor, if it takes 40sec to raise the load through a height of 24m(take g =9.8n/g)

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.

Wiy doeres rere okhn a pump whon working betwon the same pressure range?
