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
Theory of Machine A machine mounted on a single coil spring has a period of free vibration of tp . If the spring is cut into four equal parts and placed in parallel and the machine is mounted on them, then the period of free vibration of the new system will become 16 tp tp /4 4 tp tp /16 16 tp tp /4 4 tp tp /16 ANSWER DOWNLOAD EXAMIANS APP
