Air enters the rotor of an axial compressible stage with an axial velocity of 150 m/s and a tangential component of 80 m/s. The average rotor blade speed is 250 m/s. The blade angles are 48 degrees at the rotor inlet and 28 degrees at the rotor outlet (25 pts) a) Assuming the axial velocity component remains unchanged through the rotor passage, what is the change in tangential velocity ( C ) through the rotor passage

What precautions should you take to prevent injuries when dealing with heavy loads?

Afour cylinder four-stroke in-line engine has a stroke of 160mm, connecting rod length of 150mm, a reciprocating mass of 3kg and its firing order is 1-3-4-2. the spacing between cylinders is 100mm. i. show that the engine is in balance with regard to the primary inertia forces and primary 3. a and secondary inertia couples. li determine the out of balance secondary inertia force ii. propose ways of balancing this out of balance force and discuss the challenges that will arise

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.
