El moldeo de una aleación en forma de disco tiene una masa de 90.5 g. El disco tenía un grosor de 0.255 pulgadas y una sección transversal circular de 1.330 pulgadas de diámetro. ¿Cuál es la densidad? Brinde el resultado en lb/mL. D2 A =

Answer 1

Disc is in Volume circular cross section of disc = (Area of disc) (width or thick of disc) - TID thickness = F (1330 in) 2 x (0.255 in) V= 354269.157 in linch 16.387 mi) = linch = 2.54 cm linch3 = 16.387 cm3 lama almi linch3 = 16.387 m igram = 0.0022 lb mass of disc = 90.59 = 00:59) (0.00-22 lb) mass of disc = 0.1995 lb Volume = (354.269.159) (16.387 me.
