## Marks 1

Consider a slider crank mechanism with nonzero masses and inertia. A constant torque $$\tau$$ is applied on the crank as shown in the figure. Which o...
A circular solid disc of uniform thickness $$20mm,$$ radius $$200mm$$ and $$mass$$ $$20kg,$$ is used as a fly wheel. If it rotates at $$600$$ $$rpm,$$...
Which of the following statement is correct?

## Marks 2

The torque (in N-m) exerted on the crank shaft of a two stroke engine can be described as is the crank angle as $$\,\,T = 10000 + 1000\sin 2\theta -... Torque and angular speed data over one cycle for a shaft carrying a flywheel are shown in the figures. The moment of inertia (in kg.m2 ) of the flywhe... Maximum fluctuation of kinetic energy in an engine has been calculated to be$$2600$$J. Assuming that the engine runs at an average speed of$$200$$... Consider a flywheel whose mass$$M$$is distributed almost equally between a heavy, ring-like rim of radius$$R$$and a concentric disk-like feature o... A flywheel connected to a punching machine has to supply energy of$$400$$Nm while running at a mean angular speed of$$20$$rad/s. If the total flu... The speed of an engine varies from$$210$$rad/s to$$190$$rad/s. During cycle the change in kinetic energy is found to be$$400$$Nm. The inertia of... If$${C_f}$$is the coefficient of speed fluctuation of a flywheel then the ratio of$${\omega _{\max }}/{\omega _{\min }}$$will be For a certain engine having an average speed of$$1200$$rpm, a flywheel approximated as a solid disc, is required for keeping the fluctuation of spee... A flywheel of moment of inertia$$9.8$$kg m2 fluctuates by$$30$$rpm for a fluctuation in energy of$$1936 Jouls. The mean speed of the flywheel ...
