Theory of Machine A motor car moving at a certain speed takes a left turn in a curved path. If the engine rotates in the same direction as that of wheels, men due to centrifugal force The reaction on the outer wheels increases and on the inner wheels decreases The reaction on the front wheels increases and on the rear wheels decreases The reaction on me inner wheels increases and on the outer wheels decreases The reaction on the rear wheels increases and on the front wheels decreases The reaction on the outer wheels increases and on the inner wheels decreases The reaction on the front wheels increases and on the rear wheels decreases The reaction on me inner wheels increases and on the outer wheels decreases The reaction on the rear wheels increases and on the front wheels decreases 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
