Theory of Machine The advantage of the piston valve over the slide valve is that in the former case Both wear and power absorbed are low Wear is less Power absorbed is less The pressure developed being high provides tight sealing Both wear and power absorbed are low Wear is less Power absorbed is less The pressure developed being high provides tight sealing ANSWER DOWNLOAD EXAMIANS APP
Theory of Machine Angle of action of cam is defined as the angle Moved by the cam from beginning of ascent to the termination of descent 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 the instant the follower begins to rise, till it reaches its highest position Moved by the cam from beginning of ascent to the termination of descent 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 the instant the follower begins to rise, till it reaches its 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 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 ANSWER DOWNLOAD EXAMIANS APP
