Question

Tolong jawab ya kak dengan penjelasan secara perinci​

Answer 1

Titik Berat

Bidang 1

titik berat 1 = (x1,y1) = (1,1)

A1 = 2 × 2 = 4

Bidang 2

titik berat 2 = (x2,y2) = ((3,3)

A2 = 2 × 6 = 12

Bidang 3

titik berat 3 = (5,1))

A3 = 2 × 2 = 4

Titik berat bidang homogen

x = (A1 . x1 + A2 . x2 + A3 . x3)/(A1 + A2 + A3)

x = (4.1 + 12.3 + 4.5)/(4 + 12 + 4)

x = 60/20

x = 3

y = (A1 . y1 + A2 . y2 + A3 . y3)/(A1 + A2 + A3)

y = (4.1 + 12.3 + 4.1) / 20

y = 44/20

y = 11/5

Titik berat = (x,y) = (3 , 11/5) → opsi : D
