Question 1141974: a solid aluminum casting for a pulley consist of three discs each 1.5cm thick, of diameters 4cm 6cm and 8cm. a central hole 2cm in diameter is drilled out. if the density of aluminum is 2.8g/cm^³. calculate the mass of the casting Answer by Alan3354(69443) (Show Source):
You can put this solution on YOUR website! a solid aluminum casting for a pulley consist of three discs each 1.5cm thick, of diameters 4cm 6cm and 8cm. a central hole 2cm in diameter is drilled out. if the density of aluminum is 2.8g/cm^³. calculate the mass of the casting
------------
Vol = pi*(2^2 + 3^2 + 4^2)*1.5 - 3pi*1*1.5 cc
M = vol*density
