A flywheel is designed for engine speed variation from $190\text{ rps}$ to $210\text{ rps}$. Calculate the inertia of the wheel if the kinetic energy stored in the flywheel is $400\text{ N}\cdot\text{m}$.
In a slider crank mechanism for $ \frac{l}{4} $ ratio of 4, the percentage of stroke converted by the piston corresponding to 90° movement of the crank from top dead center is
The total reaction on the ground when wheels of the vehicle are subjected to the gyroscopic couple and the centrifugal force while negotiating the curve is
The point on the cam at which the pressure is maximum is known as:
For the specified flywheel design, the variation of the engine speed is from 210 rad/s to 190 rad/s. During the cycle process, the change in kinetic energy is found to be 400 N-m, then the moment of inertia of the flywheel in kg-m² is:
The extension due to self-weight of a bar of uniform cross section being hanged vertically downward is ___ times the extension produced by the same weight applied at the lower end of the vertical bar.
The relation between number of links $ (l) $ and number of joints $ (j) $ in a kinematic chain is generally
For a triple threaded screw, the lead is 30 mm and the mean diameter of the screw is 80 mm, then the pitch of the screw is
