Three masses of 2 kg, 3 kg and 4 kg are located at the three vertices of an equilateral triangle of side 1 m. What is the M.I. of the system about an axis along the altitude of the triangle and passing through the 3 kg mass?

Three masses of 2 kg, 3 kg and 4 kg are located at the three vertices

1.	Three masses of 2 kg, 3 kg and 4 kg are located at the three vertices of an equilateral triangle of side 1 m. What is the M.I. of the system about an axis along the altitude of the triangle and passing through the 3 kg mass?
Answer» SOLUTION :`I = 2 XX (1//2)^(2) + 4 xx (1//2)^(2) = 1.5 KG m^(2)`
