Theory of Machine Angle of action of cam is defined as the angle Of rotation of the cam for a definite displacement of the follower Moved by the cam from beginning of ascent to the termination of descent Moved by the cam from the instant the follower begins to rise, till it reaches its highest position Through which the cam rotates during the period in which the follower remains in the highest position Of rotation of the cam for a definite displacement of the follower Moved by the cam from beginning of ascent to the termination of descent Moved by the cam from the instant the follower begins to rise, till it reaches its highest position Through which the cam rotates during the period in which the follower remains in the highest position ANSWER DOWNLOAD EXAMIANS APP
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 (l₁ + l₂ + l₃)/3 l₁ + l₂ + l₃ l = l₁ + l₂.(d₁/d₂)³ + l₂.(d₁/d₃)³ l = l₁ + l₂.(d₁/d₂)⁴ + l₃.(d₁/d₃)⁴ (l₁ + l₂ + l₃)/3 l₁ + l₂ + l₃ l = l₁ + l₂.(d₁/d₂)³ + l₂.(d₁/d₃)³ l = l₁ + l₂.(d₁/d₂)⁴ + l₃.(d₁/d₃)⁴ ANSWER DOWNLOAD EXAMIANS APP
