Theory of Machine Two pulleys of radii r₁ and r₂ and at distance x apart are connected by means of a cross 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
