Web17 sep. 2024 · The differential area of a circular ring is the circumference of a circle of radius ρ times the thickness dρ. dA = 2πρ dρ. Adapting the basic formula for the polar moment of inertia (10.1.5) to our labels, and noting that limits of integration are from ρ = 0 to ρ = r, we get. JO = ∫Ar2 dA → JO = ∫r 0ρ2 2πρ dρ. Web27 okt. 2024 · This work is transmitted by the rod to the mass, doing work W = (ma) (rθ). Equating and dividing by θ yields: FR = (mr) (rα) = (m r 2 )α. In other words: τ = Iα where I = m r 2. This analysis can be extended to any distribution of masses or forces in a plane (or any other plane) which is perpendicular to an axle. Share.
