Four point masses of 3.0 kg each are arranged in a square on masslessrods. the length of a side of the square is 0.50m. what is the rotational inertia for rotation about an axis (a) passing through masses band c? (b) passing through masses aand c ? (c) passing through the center of the square and perpendicular to the plane of the square?

Part a)

Part b)

Part c)

Explanation:

Part a)

Moment of inertia of the system about an axis passing through B and C is given as

Part b)

Moment of inertia of the system about an axis passing through A and C is given as

Part c)

Moment of inertia of the system about an axis passing through the center of the square and perpendicular to the plane of the square

explanation:

a fuel engine ( known as a gasoline engine in american english )is an internal combustion engine with spark ignition, designed to run on petrol (gasoline) and similar volatile fuels.
