Theory of Machine The efficiency of a screw jack is maximum, when (where α = Helix angle, and φ = Angle of friction) α = 45° - φ/2 α = 45° + φ/2 α = 90° + φ α = 90° - φ α = 45° - φ/2 α = 45° + φ/2 α = 90° + φ α = 90° - φ ANSWER DOWNLOAD EXAMIANS APP
Theory of Machine A torsional system with discs of moment of inertia I₁ and I₂ as shown in the below figure, is gear driven such that the ratio of speed of shaft B to shaft A is 'G'. Neglecting the inertia of gears, the equivalent inertia of disc on shaft B at the speed of shaft A is equal to I₂/G² G.I₂ G².I₂ I₂/G I₂/G² G.I₂ G².I₂ I₂/G ANSWER DOWNLOAD EXAMIANS APP
