Theory of Machine Two pulleys of radii r₁ and r₂ and at distance x apart are connected by means of an open belt drive. The length of the belt is π (r₁ - r₂) + (r₁ - r₂)²/x + 2x π (r₁ + r₂) + (r₁ - r₂)²/x + 2x π (r₁ - r₂) + (r₁ + r₂)²/x + 2x π (r₁ + r₂) + (r₁ + r₂)²/x + 2x π (r₁ - r₂) + (r₁ - r₂)²/x + 2x π (r₁ + r₂) + (r₁ - r₂)²/x + 2x π (r₁ - r₂) + (r₁ + r₂)²/x + 2x π (r₁ + r₂) + (r₁ + r₂)²/x + 2x ANSWER DOWNLOAD EXAMIANS APP
