131. In vibration isolation system, the transmissibility will be equal to unity, for all values of damping factor, if $$\frac{\omega }{{\omega {\text{n}}}}$$ is
132. For an involute gear, the ratio of base circle radius and pitch circle radius is equal to
133. The frictional torque transmitted in a flat pivot bearing, assuming uniform wear, is
(Where μ = Coefficient of friction, W = Load over the bearing, R = Radius of bearing)
(Where μ = Coefficient of friction, W = Load over the bearing, R = Radius of bearing)
134. In a four bar chain or quadric cycle chain
135. The engine of an aeroplane rotates in clockwise direction when seen from the tail end and the aeroplane takes a turn to the left. The effect of gyroscopic couple on the aeroplane will be
136. A torsional system with discs of moment of inertia $${I_1}$$ and $${I_2}$$ 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
137. A body having moment of inertia of 30 kg m2 is rotating at 210 RPM and mashes with another body at rest having M.I. of 40 kg m2. The resultant speed after meshing will be
138. When one of the links of a kinematic chain is fixed, the chain is known as a
139. The example of completely constrained motion is a
140. The example of successfully constrained motion is a
