Question

The figure shows a composite slab with dimensions d₁ = 11.8 cm, d₂ = 3.89 cm, and d₃ = 12.9 cm. Half the slab consists of aluminum (density = 2.70 g/cm³) and half consists of iron (density = 7.85 g/cm³). What are (a) the x coordinate, (b) the y coordinate, and (c) the z coordinate of the slab's center of mass?

from - Midpoint Aluminum

Answer 1

The answer for above problem is explained below.

Chung x- coordinates x- coordinates - 12.9 cm Xcom = as : Xcom | - 6.45cm -coordinates Ycom = me I come + Maycom, a me tma - le veicom, e + lava Icom, a leve + lava = (1.858/cm?) (11.0cm) +(2,70 %) (3x140cm) 7.85 /m3 + 270 g/m²

46.315 ghz + 47.79 g/m² 10.55 g/com Ycom o my 8,9199 cm Yeon = 18.92.com z - coordinates Zcom = de Zcom = 3.89 cm Zcom = [ 1945 cm 2
