Digitizer is constructed on the basis of:
View Answer Explanation
In a four stroke I.C. engine, the turning moment during the compression stroke is
The maximum fluctuation of energy is the
The co-efficient of fluctuation of energy is the ratio of maximum energy to the minimum energy.
Which of the following statement is wrong?
The ratio of maximum fluctuation of energy to the workdone per cycle is called
If the rotating mass of a rim type flywheel is distributed on another rim type flywheel whose mean radius is half the mean radius of the former, then energy stored in the latter at the same speed will be
The ratio of maximum fluctuation of speed to the mean speed is called
The flywheel of a machine having weight of 4500 N and radius of gyration of 2 m has cyclic fluctuation of speed from 125 r.p.m to 120 r.p.m. Assuming g = 10m/s², the maximum fluctuation of energy is
A circular solid disc of uniform thickness 20 mm, radius 200 mm and mass 20 kg, is used as a flywheel. If it rotates at 600 rpm, the kinetic energy of the flywheel, in Joules is
The speed of an engine varies from 210 rad/s to 190 rad/s. During the cycle the change in kinetic energy is found to be 400 Nm. The inertia of the flywheel in kg/m2 is
