Theory of Machine Two heavy rotating masses are connected by shafts of lengths l₁, l₂ and l₃ and the corresponding diameters are d₁, d₂ and d₃. This system is reduced to a torsionally equivalent system having uniform diameter d = d₁ of the shaft. The equivalent length of the shaft is l = l₁ + l₂.(d₁/d₂)³ + l₂.(d₁/d₃)³ l₁ + l₂ + l₃ l = l₁ + l₂.(d₁/d₂)⁴ + l₃.(d₁/d₃)⁴ (l₁ + l₂ + l₃)/3 l = l₁ + l₂.(d₁/d₂)³ + l₂.(d₁/d₃)³ l₁ + l₂ + l₃ l = l₁ + l₂.(d₁/d₂)⁴ + l₃.(d₁/d₃)⁴ (l₁ + l₂ + l₃)/3 ANSWER DOWNLOAD EXAMIANS APP
Theory of Machine In a four-bar chain it is required to give an oscillatory motion to the follower for a continuous rotation of the crank. For the lengths of 50 mm of crank and 70 mm of the follower, determine theoretical maximum length of coupler. The minimum length of the coupler will be 95 mm Slightly less than 45 mm Slightly more than 45 mm 45 mm 95 mm Slightly less than 45 mm Slightly more than 45 mm 45 mm ANSWER DOWNLOAD EXAMIANS APP
Theory of Machine In a flat collar pivot bearing, the moment due to friction is proportional to (r₁³ - r₂³)/(r₁² - r₂²) (r₁³ - r₂³)/(r₁ - r₂) (r₁² - r₂²)/(r₁ - r₂) (r₁² - r₂²)/(r₁ + r₂) (r₁³ - r₂³)/(r₁² - r₂²) (r₁³ - r₂³)/(r₁ - r₂) (r₁² - r₂²)/(r₁ - r₂) (r₁² - r₂²)/(r₁ + r₂) ANSWER DOWNLOAD EXAMIANS APP
